Who has tried this spray TB cleaner that you spray in the throttle body with the car running...does this actually work..im looking to try anything to fix my erratic idel. I have a new MAF sensor, New Ac delco plugs and wires, New airfilter,new 02 sensor, new fuel filter, and pcv valve, nothing has helped my **** poor mileage or erratic idel, it runs very rich and gets around 11-13 mpg in town! ouch! Also the PCM isnt giving me any codes so im assuming its nothing in the computer area. But in park if i rev it up there is a banging sound comming from the engine compartment then when i release the accelerator it makes a hard CLICK noise the the car rolls a few inches back or forward, it also does this in neutral.

Well I've tried just about EVERTHING in the last twenty or so years. TB cleaner isn't going to help. Sorry. A good cleaning of the TB itself might be in order though for starters. Have you had the TPS checked? Are the TPS mounting bolts tight?
As for the "banging" sound, well that sounds like a motor mount needs to be replaced.

the whole motor mount thing would make sense cause in drive at idel i can feel the car running, its like everything in the car is rattling especially the steerwheel. I can tes the whole motor mount but using a crowbar and trying to move the mount around right??

Some of them you can....but most of the 4 you can't. Best way to test them is to have someone inside the cvar, shifting from reverse to drive again while having their foot on the brakes. You can then look at each mount in turn to see which one has the excessive movement.

TPS should set a code 21 or 22. The PCM seems to be pretty sensitive about this one.

Does your torque convertor still lockup cruising in overdrive? If so, there is no TPS problem.

Theres no sutch thing as a mechanic in a can; tear it down do it right!!

Use the code scanning procedure in Techinfo. Come back here with any codes. I have seen one TPS with a big 'dead spot' that wouldn't throw a code, but prevented the Cruise Control from working. I still have that one. Saving it for the grandkids.

Yes but he'* having trouble at idle. PCM has a very narrow range of voltage outputs from TPS it'* happy with at idle.
