used car to us. colorado november weather clear but 50 degrees, down to 10 degrees at night. went on 2day 500 mile trip. service engine soon light on. refitted gas cap and continued trip and filled car again- light still on. traction controll. tcs light and slip warning occationaly on and reset after stopping and resetting as per operators manual instructions -car would not go over 15 mph while slip warning light on. this may be a coincidence that is happing at the same time,may not be related. returned home after doing several car off and on cycles. parked car in driveway overnight then started next day and pulled in garage to park,10 second run- 10 minutes later tried to start car and no fire. car turns over fine. car will not fire 12 attempts. wrecker service to garage and garage pulls front 3 plugs and says plugs fuel fouled. trouble code read-#1121 tp sensor. next day in warm garage and replacing the front 3 plugs, remove map inlet and cleans by blowing with breath- engine starts. cleared codes and no warning lights or problems. driving fine rest of day. any ideas? thank for help.

 

TP sensor huh. That might foul your plugs alright. Well, if it's running well now I guess I'd just replace the rest of the plugs and see what happens. Might just have been a loose connection at the TP sensor or something. Wouldn't hurt to run it for codes again just to be sure.

 

Definitely have it scanned for codes. If that many lights are coming on there is probably a good chance something major has happened. its not unheard of that ecm could go bad. Or a combo of O2 sensors and abs sensors. If all that was found on the codes was tps sensor than its probably all it was.
