SOURCE: truck back fires when accelerating

Sure sounds like a lifter is clogged or a valve is hanging partially open.
Think about oil changes. Some have used kerosean (sp) in the oil for a few hundred miles before changing it - just to clear out the lifters and clean the oil feed channels and valve guides. Just don't drag race with a cleaner/thinner in your oil pan.....

At the time you made all the above repairs, did you replace the "throw away" turbo charger? The turbo charger commonly sucks oil, and it is not repairable.

Run it without the inner & outer air cleaner. If it isn't the turbo, run the injector cut out test. If the injectors are ok, then you need to replace the injection system hydraulic pump, which is also unrepairable.

Depending on what kind of truck you have it may be the distributer. I have a 72 ford pk and same problem. Changed points and same problem. Changed distributer and fixed problem.

SOURCE: rough running when engine is cold

It can be issue with IAC( idle air control valve) causing the problem.


There are many other possibilities causing these idle issues. Engine idles rough.

There are few help links with solutions to troubleshoot such idle issues.

I suggest you refer the link below and follow its troubleshooting details:------

Testing

Check the Manifold Absolute Pressure (MAP) sensor circuit as follows:
Ignition OFF, disconnect the MAP harness connector at the MAP sensor.Ignition OFF, test for less than 5 ohms of resistance between the low reference circuit terminal 2 and ground.If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.Verify the scan tool MAP Sensor parameter is less than 1 kPa.If greater than the specified range, test the signal circuit terminal 3 for a short to voltage. If the circuit tests normal, replace the ECM.Install a 3A fused jumper wire between the signal circuit terminal 3 and the 5-volt reference circuit terminal 1. Verify the scan tool MAP Sensor parameter is greater than 126 kPa.If less than the specified range, test the signal circuit terminal 3 for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If all circuits test normal, test or replace the MAP sensor.

Check the Throttle Position (TP) sensor circuits as follows:
Ignition OFF, disconnect the harness connector at the throttle body.Ignition OFF for 90 seconds, test for less than 5 ohms of resistance between the low reference circuit terminal C and ground.If greater than 5 ohms, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM. Ignition ON, test for 4.8-5.2 volts between 5-volt reference circuit terminal E and ground.If less than 4.8 volts, test 5-volt reference circuit for a short to ground or an open / high resistance. If the circuit tests normal, replace the ECM.If greater than 5.2 volts, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 1 voltage is less than 0.1 volt.If greater than 0.1 volt, test the signal circuit terminal D for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 2 voltage is greater than 4.8 volts.If less than 4.8 volts, test the signal circuit for a short to ground. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal D and the 5-volt reference circuit terminal E of the TP sensor 1. Verify the TP sensor 1 voltage is greater than 4.8 volts.If less than 4.8 volts, test the TP sensor 1 signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal F and the low reference circuit terminal C of the TP sensor 2. Verify that the TP sensor 2 voltage is less than 0.1 voltIf greater than 1.0 volt, test the TP sensor 2 signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the ECM. Ignition OFF for 90 seconds, disconnect the harness connector at the ECM.Test for less than 5 ohms of resistance on all TP sensor circuits between the following terminals:ECM C2 signal circuit terminal 65 to TP terminal DECM C2 signal circuit terminal 63 to TP terminal FECM C2 5-volt reference circuit terminal 3 to terminal E If greater than 5 ohms, repair the affected circuit for open/high resistance.Test for infinite resistance between TP sensor 1 signal circuit terminal D and TP sensor signal circuit terminal F.If less than infinite resistance, repair the short between TP sensor 1 signal circuit and TP sensor 2 signal circuit. If all circuits test normal, replace the throttle body.

Throttle Body Relearn Procedure
NOTE
Do NOT perform this procedure if DTCs are set.

Start and idle the engine in PARK for 3 minutes.With a scan tool, monitor desired and actual RPM.The ECM will start to learn the new idle cells and Desired RPM should start to decrease.Ignition OFF for 60 seconds.Start and idle the engine in PARK for 3 minutes.After the 3 minute run time the engine should be idling normal.
NOTE
During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.

If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
After the drive cycle, the engine should be idling normally.

If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.Once the engine speed has returned to normal, clear DTCs.

Drive cycle


Here is the OBD2 emission system drive cycle test procedure.
Engine coolant temp must be below 70c (158f) before starting the engine for either the first or second trip
The fuel level should be less than 1/2 full
First trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" for at least 10 seconds (not more than 5 min)
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary.
End of first trip. Turn the key off the begin the second trip.
Second trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" add four gallons of fuel
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary. I especially like the part where they want you to add four gallons of fuel. Not three gallons, not five gallons, four gallons. Gotta love those Nissan engineers. ...and of course they state that if the trace is not followed exactly (i.e. you botch the acceleration/deceleration) you have to start all over again from scratch

Starts fine and the engine will idle then it will die from idle try to accelerate and it seems like its out of fuel replaced feul filter no change friend says its the catyletic converter but it happened...


here are the converter symtoms: decreased low rpm power, engine runs a little hotter then normal at cruising speed, exhaust leaks near header, bucking or jerking during accelerating, cats exterior surface temp cooler near outlet. if you suspect the cat of being bad take it to a garage, to find out for sure if it is, have a good day !!

My xj6 runs at high rpms and accelerates on its own


None of those possible problems have anything to do with idle speed. The first thing might be a very weak throttle return spring. The next would be a sticky throttle cable or foot feed pedal that isn't moving freely. Another possibility is a vacuum leak somewhere. Did changing the spark plug in #1 cylinder help the misfire? If not, you may have a partially plugged injector. Fixing the misfire will only increase idle speed some more. Look for an idle speed motor near the throttle body that is supposed to raise idle speed when the engine is cold and lower it back when the engine warms up. Check to see if it is holding the speed too high. If the throttle position sensor tells the computer where the idle speed motor is set, then it could have an effect on idle speed if the sensor is bad. The position sensor is just a fancy potentiometer. Hope some of this helps.
