Throttle body cleaner
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.

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??

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.

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.
