Ok here's the full scoop 2 days ago I put a thermostat in my 04 2.2 Eco sunfire auto and took it for about a 20 min drive I was about a mile from home when my trac-off light came on, I drove it home and their was no codes so I disconnected the battery to reset the pcm. So then I took it out for another drive and all of a sudden about 5 mins down the road the cel came on giving me the p0113 code...... I cleared that when I got home it then cleared the trac-off and pcm codes so I decided to take it for a spin again and 5 mins down the road the trac-off came on again I did this procedure like 3 more times and inbetween here and their I replaced both front speed sensors the IAT and the tps..... Then the last time I took it out the trac off came back on so I drove it home and then while it was parked the cel light came back on giving me the same IAT sensor high output code. Now for how the car is acting before the trac off light comes on it spits and sputters till the light comes on the once the trac off light is on it slams into gear going front first into second is the worst and I do notice a loss in power, I am completley clueless and don't know what else to do.....

So.today I got the codes scanned it said it was. The IAT and the driver side wheel speed sensor about 5 times in the last 2 days and the trac off light and IAT code keeps coming back on for the cel and also the trac off engages when the fan comes on so I have no clue what can be doing this does anyone have any clue what to do..... I replaced the tps the left and right wheel speed sensor and the IAT and still don't know what else I can do to resolve this problem....
