so i clean the tps sensor and surrounding area with carb cleaner. and now it doesnt want to idle. it would just bob and then rev and i would hear a pop now and again. Heres a video of whats going on.

That is weird....

Hopefully you won't be at the front of a red light while that is happening.

I'm guessing you ruined something, why did you clean the tps with carb cleaner in the first place? If there was nothing wrong with it, why mess with it.

this is why i did it

Yo Saif, if you can bring it over to my house, ill take a look at it. The TPS can be tricky sometimes.

can you come to mine? im not not driving the beast like this lol. i live in the galleria area

so i changed both tps and icv. i even switched ecu. someone please help

how about distributor... did u do anything with it...

I think it is TPS... did u change it by yourself...

have someone look at it...

i already changed it every thing so we don't know hey zeeshawn i thought you were gonna come check it out that one day

I changed The icv and the tps, i havent touched the distributor since the last tune up which was about 4 months ago. Could it be the maf sensor?

Did you adjust the gps after you reinstalled it? U can't just throw it in and call it a day

d1 is right. The TPS MUST be set to proper voltage for it to operate properly, and for it to deliver proper signal to the ecu. variations/fluctuation in idle like that can be cause by TPS, IAC, Ignition/timing, coils, bad grounds, vacuum leaks, and I can keep going...You need to check to see what codes are coming up with the associated CEL, and eliminate the issue(s) not related to the TPS/IAC. Also cleaning electrical sensors/components with carb cleaner isnt the best ideal, find a can of LPS dielectric cleaner for components like that.

oh yea turbo brought up a good point.... Why the F@(k would you use carb cleaner on a sensor? You do know that carb cleaner leaves a residue. ALWAYS use electric parts cleaner on sensors?

im sorry i cleaned the throttle body with carb cleaner not the tps. it was removed while i was cleaning it tho. thanks for your help im going to start off by calibrating the tps and go from there
