Tpi 2010897/7 - Volkswagen Cars & Trucks

Best thing go to www.reliable-store.com they have got books on every vehicle and also how to service/repair it,

service/repair/owner's/maintenance manual with
parts info, fuse box, gear box, PCV, torque specs,coiling, wiring diagrams, electrical diagrams, fuse diagrams, error codes, etc everything

Worth it

fill all tires to correct pressure the tpi will reset automatically --if you have dash instead of a pressure number that tpi valve has failed and will need replacing

Are you trying to use your harness and ecu from the existing v6? Please say no cuz the ecu for a v6 will not work well for the v8. I would suggest getting the ecu harness from the vette you got the motor from. GL.

If you mean lean, check your Oxygen sensors

if no tag is under the hood for emissions controls..look it up by car make and model for emmisions or call parts store for printout..

Great. Intermittant issues are a real annoyance. You need to become the detective and start monitoring the vehicle. At the times that it hesitated, did you feel anything slightly different, like a rougher idle? Many things can cause your condition. One high on the list is a throttle position sensor (TPI), often they are an electric volume switch, and it sends info to the computer, well the most used area for the control is off idle...You should be getting error codes before too long. The TPI unit is high failure area.

idle air control is used for assisting in fold starts. It sounds like its not functioning propperly. FYI your car is not carberated, its called a throttle body.

change the egr valve and also change the o2 sensor.

check your voltage readinf for you tpi sensor it should be a value of 0.0_ on the output side when you are at an idle. I think the bad tpi sensor. Let me knoe [email protected]

Does it run poor at full throttle or between quarter and half throttle? Does it hessitate? If it does the EGR valve may be worn out. I had an 87 transam with TPI and was having problems with it stumbling and hesitating when it was warmed up. If the car starts hard and you have these problems then the issue may be low fuel pressure. Hook a guage up to the fuel rail and make sure you are getting pressure. If you are only getting a few pounds of pressure it may be the fuel pump or fuel pressure regulator. Good luck and if you thought this information was helpful please rate it when you get a chance.
