dont take soo much in consideration after you have make all this things, some time is on only for any wire faulty, or a shrt electrical arc in any place in wire system. ask auto tap mechsnics for this maybe they have similar case before.

SOURCE: upper engine knock

I had the same problem with my 1999 Cobra Convertible, it sounded like valve problem, but ended up being, a wrist pin noise! Replaced the enging and trans, found a new Engine thru Trans, with everything on it for $4300, sold the old one (with the noise) on e-bay, for $4300 plus shipping.
The drivetrain now has about 10k miles on it, no problems! Have someone check for wrist pin noise!
This is a Roush Cobra Convertible, I will sell for $12,500, with a new top! Pictures avalible!

SOURCE: timing slipped will it bend intake, exhaust or both sets of valve

First of all, you'll want to perform what's called a 'LEAK-DOWN' test. The assumption you make (regarding Intake versus exhaust) is irrevelant. Interferrence is BOTH intake and exhaust valve clearances. A leak down or "cylinder leakage" test is similar to a compression test in that it tells you how well your engine's cylinders are sealing. But instead of measuring pressure, it measures pressure loss.
A leak down test requires the removal of all the spark plugs. The crankshaft is then turned so that each piston is at top dead center (both valves closed) when each cylinder is tested. Some people start with cylinder number one and follow the engine's firing order.
A threaded coupling attached to a leakage gauge is screwed into a spark plug hole. Compressed air (80 to 90 psi) is then fed into the cylinder. You don't have to use that much pressure... you can use 30 psi... percentages are the same.
An engine in great condition should generally show only 5 to 10% leakage. An engine that's still in pretty good condition may show up to 20% leakage. But more than 30% leakage indicates trouble.
The neat thing about a leakage test (as opposed to a compression test) is that it's faster and easier to figure out where the pressure is going. If you hear air coming out of the tailpipe, it indicates a leaky exhaust valve. Air coming out of the throttle body or carburetor would point to a leaky intake valve. Air coming out of the breather vent or PCV valve fitting would tell you the rings and/or cylinders are worn.
A leakage test can also be used in conjunction with a compression test to diagnose other kinds of problems.
A cylinder that has poor compression, but minimal leakage, usually has a valvetrain problem such as a worn cam lobe, broken valve spring, collapsed lifter, bent push rod, etc.
If all the cylinders have low compression, but show minimal leakage, the most likely cause is incorrect valve timing. The timing belt or chain may be off a notch or two.
If compression is good and leakage is minimal, but a cylinder is misfiring or shows up weak in a power balance test, it usually indicates a fuel delivery (bad injector) or ignition problem (fouled spark plug or bad plug wire). These are not ABSOLUTE conclusions -- each assumption must be VERIFIED before concluding anything. You mentioned "the lifters seem to be collapsed."... Did you VERIFY this? Since you KNOW the engine is OUT - OF - TIME because you KNOW the timing belt has SLIPPED, then you know you must PUT IT BACK IN TIME... right?...before you can continue diagnosis.... right? Otherwise, what are you MEASURING?

IMR - Inlet Manifold Runner valve


1.10) IMR- Inlet Manifold Runner valve (actuator)

What is it? The inlet manifold consists of a plenum chamber onto the front of which is mounted the throttle . Extending from the plenum is a series of moulded pipes called 'runners' curve round to the intake ports on the cylinder head. In some instances there are two intake ports for each cylinder fed by slightly different lengths of runner. When the engine is at low revs the longer pipe works well. However at higher speeds the shorter length of the alternative runner is better suited. To cater for this the shorter port, which is normally shut off at low engine speeds by a plate (very similar in operation to the throttle plate), is opened by a motor or solenoid. The shorter runner is usually opened in addition to the longer runner and not as a substitute. The opening of this additional shorter runner is done by the IMR.


Where is it located? The IMR valves are located in the throat of each inlet port and the controlling motor is located at the end of the interconnecting shaft.

How does it work? At a predetermined engine speed (>3000rpm) the ECU sends a voltage to the IMR that snaps open the additional inlet portsto boost power output. It does this by either a) directly with an electrical motor or b) it opens a solenoid valve and allows vacuum, sourced from the inlet manifold, to act on a diaphragm to rotate the valve shafts.

Symptoms of a faulty IMR
Associated OBD2 error codes DTCs: P1500 - P1599

  • Power reduction - If the IMR fails to open in the upper rev range the engine will seem to lack any (power) 'head-room'. The engine will still operate but the usual additional power boost in the upper rev range will be absent.

How to Check? Visually check the action of the action of the actuator in response to increasing engine speed.

How to Fix? Check the wires and connections. If the device uses a vacuum, check the tubing for leaks. If the IMR unit is faulty replace it.

Is your check engine light on ? Any codes ?

There are three basic types of intake air sub-systems:


  • Intake Manifold Runner Control (IMRC) electric actuated system

  • Intake Manifold Swirl Control (IMSC) vacuum actuated system

  • Intake Manifold Tuning Valve (IMTV)

These subsystems are used to provide increased intake airflow to improve torque, emissions and performance. The overall quantity of air metered to the engine is controlled by the throttle body.

Intake Manifold Runner Control (IMRC) Electric Actuated System
The Intake Manifold Runner Control (IMRC) Electric Actuated system (Figure 107) consists of a remote mounted motorized actuator with an attaching cable for each housing on each bank. Some applications will use one cable for both banks. The cable or linkage attaches to the housing butterfly plate levers. The 2.0L (2V) Focus IMRC uses a motorized actuator mounted directly to a single housing without the use of a cable. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder. One passage is always open and the other is opened and closed with a butterfly valve plate. The housing uses a return spring to hold the butterfly valve plates closed. The motorized actuator houses an internal switch or switches, depending on the application, to provide feedback to the PCM indicating cable and butterfly valve plate position.



Below approximately 3000 rpm, the motorized actuator will not be energized. This will allow the cable to fully extend and the butterfly valve plates to remain closed. Above approximately 3000 rpm, the motorized actuator will be energized. The attaching cable will pull the butterfly valve plates into the open position. Some vehicles will activate the IMRC near 1500 rpm.



WARNING: SUBSTANTIAL OPENING AND CLOSING TORQUE IS APPLIED BY THIS SYSTEM. TO PREVENT INJURY, BE CAREFUL TO KEEP FINGERS AWAY FROM LEVER MECHANISMS WHEN ACTUATED.




  1. The PCM uses the TP sensor and CKP signals to determine activation of the IMRC system. There must be a positive change in voltage from the TP sensor along with the increase in rpm to open the valve plates.




  1. The PCM uses the information from the input signals to control the IMRC motorized actuator based upon rpm and changes in throttle position.




  1. The PCM energizes the actuator to pull the butterfly plates open with the cable(s) or linkage.




  1. The IMRC housing contains butterfly plates to allow increased air flow.

My engine light is on i have code p 1516 come up. i have power failure while driving it will say service traction control of and then reduce engine loss power.i have to pull over and cut it off for a lil...


P1516 IMRC Input Error (Bank 1) you have a dual stage intake,, which is controlled by the IMRC,, what you need to do is rev the motor to around 3200 rpms,, and check to be sure that the cable is letting the unit open and close correctly, something is sending the code because its not working correctly which would give you the results that your experiencing, most of us back yard mechanics can't do much with these set ups and would have to take it in to a certified shop that has the correct tools to repair this code and its faults .

Error code 1159 told by the dealer it needs a part that cost over $500


The 3.0L and 3.5L engines in the XG300, XG350 and Santa Fe incorporate a Variable Induction System (VIS). The VIS is a secondary set of throttle plates in the upper intake plenum used to increase low end torque while maintaining high rpm performance. The Powertrain Control Module (PCM) uses a Variable Intake Motor (VIM) to control the opening and closing of the additional throttle plates called the Intake Control Valve (ICV).
At low rpm the (ICV) is closed and, as rpm increases, it is opened a specified amount for optimum airflow.
A VIS system condition is not likely to affect drivability, however, a diagnostic trouble code (DTC) may set. The DTC for the VIS system is P1159 (Variable Intake Target Position). The PCM controls the desired valve position and when the feedback of the
valve position does not correlate with the requested position this code is set. This DTC will not turn the check engine lamp on, however the code will remain in memory.
NOTE: P1159 has been changed to P2015 for the 2005MY.
Please refer to DTC P2015 in the 2005 Shop Manual for further diagnostic information on P1159. (XG350: page FL-555) (Santa Fe: page FL-633)
DTC DETECTING CONDITION:
ITEM DETECTING CONDITION POSSIBLE CAUSE
DTC Strategy Target position monitoring • Poor connection
• Open or short to battery
in harness
• VIS Motor or VIS Motor
Rotation Sensor
• PCM
Enable Condition Engine speed > 3750 rpm
Threshold Value Unable to obtain target value
Diagnosis Time Unable to obtain target position 4 times
MIL On Condition N/A

The VIM is not available as a separate unit from the upper plenum if replacement is needed, therefore the entire plenum assembly must be replaced.
NOTE: With the intake plenum removed, inspect the gear on the VIM to see if it has stripped. Carefully inspect the throttle plate retaining screws that attach the plates to the VIS shaft. If any of the screws are missing (2 screws per throttle plate) inspect for engine damage.
Once the intake replacement is completed (see appropriate Shop Manual for the vehicle you are working on) the Electronic Throttle Position System (ETS) should be re-initialized by turing the ignition key On and Off within 1 second. Then, wait 30 seconds before starting the vehicle. Refer to TSB 05-36-002 for the complete ETS
initialization procedure.
