I recently replaced my TPS and adjusted it according to advice on here. Took the car for a drive tonight....started acting up... Apparently I didn't tighten the TPS enough....got that fixed....

Now getting MAF Voltage too high....can I adjust this too or do I need new MAF???

 

I re-adjusted the TPS, no more ses light car is running better... My idle is a little weird at times though... This morning I had it in Drive and was just sitting when all of a sudden the idle went up to about 1200 (in Drive) I have my diagnostic computer hooked up. TPS is still correct. I put it in park, idle is about 1500, I crack the throttle... Idle comes down and car dies. Fires right back up, drove it about 15 miles to work, all was well. When I put it in park at work, idle was back up to 1500.

Any ideas???
