I left work today and noticed that I have to floor it to get any accel in the car. At about 3k and under half throttle, the car starts to spudder and buck on me unless I go at WOT. Never has happened before. I pulled off at a shop to run in and buy a few things and when i got back out, I was having a hard time getting it to stay running. I would start up and die right away. I couldnt give it any gas as the peddle was feeling different than usual. Never done any of this before. Any ideas?

 

have you checked your TPS?

 

not yet. Im not exactly sure what I should check for. It was running great and then suddenly it started bugging out. Does the tps go out that suddenly?

 

mine started doing this to a while back.....
just went really rich via wideband...
it was like 9:2 and it should be like 11:5
i still dont know what sup

 

Have you looked up "spudder" in a dictionary?

It sounds like a large vac leak. Thoroughly inspect all of the plumbing, particularly the TID which has a tendancy to crack from age. It could also be a loose or broken injector plug, but you'll have to pull the UIM to check them.

Why would you? How would a TPS cause these symptoms? If you don't really know, please don't throw out random guesses.
