Throttle position sensor or mass air sensor, more than likely TPS sensor going bad and hasn't thrown code yet.

SOURCE: car won't idle after battery change

Won't idle after battery change... SOLVED! well, for me anyway. :)

I just experienced the same problem on my 2002 tundra last night, and fixed it this morning after sleeping on the problem. Here's how it went.
I cleaned the terminals, etc., and replaced the battery, as it was 7yo and old and on the verge of failing.
Immediately after this, the truck would start right up but the idle would drop to about 100 RPM, then slower and slower, and eventually stall. Every time.
I warmed it up and drove around the neighborhood for about 45 minutes, thinking the computer needed to re-learn it's Idle settings, etc... No change.
This morning, I decided to go after the cheap and easy fixes first...
Inspect throttle body... it was filthy full of black sticky dirty/sludgy stuff. I cleaned it off using a rag and some brake cleaner. DID NOT spray brake cleaner IN the opening; just on the rag and then wiped all of the gunk out of the opening, butterfly, and inside as far as my fingers would reach with the butterfly open.
Reassembled everything, started truck... runs perfectly.

Dead battery? Won't run? Dirty throttle body? How do these all tie together?! Here's why (to the best of my understanding).
Over the past 65k miles, dirt and gunk slowly but surely builds up in the throttle body. At some point, the computer senses that this affects the air/fuel mixture or something of this nature. The computer compensates for this, and stores it to it's memory. Sometime during the vehicles lifetime, the battery fails or is disconnected. The compensation settings that the computer stored are lost when the power is disconnected, so the next time the engine is started it's telling everything to behave as default... but the car isn't in a default state, there's **** in the throttle body... or a bad sensor, etc.
I could be way off, but my gut feeling is that this is correct. My advice: Pull the intake tube off the front of the engine and clean the gunk out of the throttle body. It should be the first thing to try, since it's the cheapest and easiest thing that I can think of.

Your catalytic converter is plugged up,  If you check the exhaust output at the tailpipe you will find it restricted.
Let me know if I  can assist further.

1999 audi a6 shakes, in ocations violently. Raw fuel smell. Loss of power. Burnt oil smell. idles poorly


If you had the ecu read it would probably say egr code. also a number of other codes to do with injectors and co2 sensor. you need to clean out the egr and clean out the air vent pipe from the sump to the top. also clean out the idle valve on the in take. also the breather pipes. you may even need to change the air filter. and when was the fuel filter changed. an oil change a filter change would not go a miss if it has not been done in awhile. routing maintenance will stop this happening again.

I have a 1992 Pontiac Bonneville. The car idles rough and idles at about 600rpm which seems a little low to me. Also it will stall after driving it for 15-20 minutes. After stalling it usually will not...


sulfer smell would be your egr valve not working. as far as stalling check the signal at crank sensor . also when your checking, maybe replacing the sensor check and make sure your harmonic balancer isn't broke. check rubber mounting surface for any melting and stuff like that..
