SOURCE: rpm hunting

check for a vaccuum leak this is where i would start if it rolled into my shop. possibly a PCV valve sticking or a hole in the hose, this hose should run from the valve cover, or crank case and then to the intake, or carb.

SOURCE: 1994 toyota pickup rattles at low speeds (~15-19 mph).

On 22RE engine you may have bad chain tensioner or chain guid .Very common problem , you better take care of it now because chain may cut through front cover which is also water pump housing and then coolant goes to the oil pan.

Loss of engine power/transmission 2001 chevy tahoe over 65 mph


Sound's as though a previous owner installed a speed governor so that the engine would not exceed the nationwide 55-65 mph speed limit average. This most likely was a company owned vehicle or owned by someone concerned about speeding ticket's or excessive speed by a teenage driver. It can be uninstalled by an experienced mechanic. Unless this poses a problem while driving on an interstate, you may wish to leave it as is.

Vehicle will accelerate to 20-25 mph, then it feels as thoughit goes into neutral. It will not accelerate, the rpm's increase, that's all. It is as though it won't engage into the higher gears or...


Sounds like you are onto the problem.
You may have lost 3rd gear. If its an automatic you'll need a transmission shop to check it out.

Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

What does the code p1734,p0780 mean and how do i slove it


P0780 Automatic Transaxle Malfunction (With Automatic ...


























P0780 Automatic Transaxle Malfunction - With Automatic Transmission





Possible Causes


Setting Conditions







  • Mechanical problems present in the automatic transmission can cause this code to set. See the note below.


  • Refer to the repair instructions in a transmission repair manual or the information in other electronic media to repair this code.




Engine running; vehicle driven at Cruise speed, and the PCM detected a problem in the mechanical operation of the automatic transmission. Note: This trouble code (P0780) sets with along with several TCM related trouble codes.he





Malfunction Indicator Lamp

The Malfunction Indicator Lamp (MIL) alerts the driver that the Powertrain Control Module (PCM) has detected an OBD II emission-related component or system fault. When this type of malfunction occurs, an OBD II Diagnostic Trouble Code (DTC) will be set by the PCM. The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON, or is identified with an ISO standard engine symbol (i.e., a picture of an engine).

Bulb Test

Each time the ignition switch is turned to the "on" position, the MIL indicator is illuminated for about 3 seconds (which is a function of the PCM).

Readiness Codes

To check if the Readiness Codes are set to complete, turn the ignition switch "on", but do not start the engine. The MIL will come "on" for 15-20 seconds. If it then goes "off", the Readiness Codes are set to complete, If it flashes five times, one or more of the Readiness Codes are not set to complete. To set Readiness Codes from incomplete to complete, perform the drive cycle procedure for the appropriate code.

MIL Lamp-On Message

Each time the PCM detects an Emissions related fault, the MIL is illuminated to inform the driver that the vehicle needs to be taken in for service.




COMPONENT MONITOR DRIVE CYCLE INSTRUCTIONS



  • Do not turn off the ignition switch during the test procedure.


  • All Onboard Diagnostic Monitors are cleared when the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the Scan Tool.


  • This drive cycle can be used to determine if the Readiness code for this Monitor will run and complete, and if the MIL will remain off after the vehicle is driven.


  • Operating Ranges: When a range of values is provided, try to operate the vehicle in the middle of the range. For example, if the vehicle speed range calls for 45-55 mph, drive the vehicle as close as possible to 50 mph. If the engine speed should be 1,000-2,000 rpm, try to operate the engine at 1,500 rpm.


  • Scan Tool Data: There are certain Parameter Identification (PID) values that must be within range before this Monitor will "run". It can be helpful to pull up those PID items on the Scan Tool so an assistant can view them during testing.


  • The Readiness code for this Monitor defaults to "continuous" or "monitoring" because this Monitor runs continuously when the engine is cranking or running.




COMPONENT MONITOR PRETEST CONDITIONS



  • MIL is off.


  • No Emission related DTC's are present.




TEST PROCEDURE



  1. Connect the Scan Tool to the data link connector (DLC). Use the Scan Tool to clear any stored DTC's and to reset the OBD Monitors.


  2. Start the engine and allow it to run at idle speed for 15 seconds.


  3. Accelerate at part-throttle to 40 mph and maintain that speed for several minutes. Bring the vehicle to a stop, and then allow the engine to idle with the transmission in Drive (in Neutral for M/T) for 15 seconds.


  4. Then accelerate at moderate throttle to 50 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop, and then accelerate to 40 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop and allow the engine to idle for 15 seconds. Repeat this step at least 5 times.


  5. Check for any Pending codes in the Generic OBD II section of the Scan Tool. If no Pending codes are set, the Component Monitor test is complete. If any Pending codes are set, refer to the appropriate trouble code repair information to make the repair.

I think my automatic transmission modulator valve is going out because it jerks and vibrates when i accelerate anything above 50 MPH.


90 % of the time jerking or vibration is usually caused by the engine and not the transmission. The most common cause is cylinder misfiries caused by the ignition system that cause the vehicle to ****, stumble, or shudder which make it appear and feel as though the transmission is the cause. Most transmission problems will cause harsh shifts, slippage, and/or delayed engagement but rarely jerks or vibrations. I'd start by looking at the spark plugs, plug wires, and coil packs to make sure they are all ok first before going any further. The reason most of these problems are more noticable over 50 mph is that the torque converter clutch is engaged at this point and it provides a solid connection between the engine and drivetrain which makes engine misfires more noticable. Good luck, hope this helps a bit!

1985 4Runner 22RE (injected / auto trans) has NO accelaration.


From minor problem to major problem. Try to replace your spark plug wires, rotor cap and the spark plugs, also it can be the injectors, plus if possible, try to replace the fuel filter which is located low under your EFI unit. If problem not solved, then it will probably be your A/T trans.
