1 Answer

Check engine light was on, replaced the throttle body light was reset, the car ran much better and no light, but didn't pass inspection, 300 miles later light comes on and the engine code is for both sides runner controls; the odds of the two sides going at the same time seems impossible, how can this be fixed?

Actually, I believe both runners are switched by the same vacuum switch. It may be that switch that has failed. Trace the vacuum lines from the actuators on the end of the manifold back to the vacuum switch and test it for operation. I think it hangs off the back of the inlet system close to the firewall (really hard to get to) :o(

You need to determine if the ETC Failsafe is from a
bad throttle body motor (TACM) or coil misfires that are
putting it into failsafe.

The TPS Sensor you replaced,wasn't likely the issue.

Resetting throttlebody on 1998 be jetta glx

you can reset it by removing negative battery terminal while leaving positive terminal connected . open driver side door get in close door , put key in ignition turn over key almost all the way but do not start . you should here the throttle body aligning itself . leave key in this position for 15 seconds , remove key connect negative terminal and the throttle body should be set . this has been called the chicken dance and it works fine . what this does is resets the computer , key note though if you are planning to get your car inspected it will not pass until you have drove the car for at least 300 miles . being that the computer has to go through and set everything . i learned the hard way . throttle body problems usually happen when removing old battery improperly/battery being drained/improperly or jump starting the car/improperly , make sure when removing battery that the positive terminal is removed first , jumping a battery negative terminal is always connected first on both vehicles .

Rough idle 1994 chevy pick up k1500 4x4

I had a 96 GMC 1500 with a 5.7 ltr. It would idle rough, especially on start up. After replacing everything under the sun, it turned out the ECM (computer) was shot. I found a used one and plugged it in and it ran fine. I think I paid 50 bucks or so for it. If you know someone with a truck like yours, plug theirs in and see if it fixes it.
