I am unsure of what my problem is but here are the symptoms: Fails to start, unless I play with the gas pedal. Sometimes it starts, but you can hear it lag for a second before it takes. (if that makes sense) Sluggish when speeding up and seems to struggle on the higher RPMs. (Like it doesn't have enough energy) some backfire when down shifting. (this doesn't occur all the time) TFI module is not hot after driving (does this matter?) Car does not shut off by itself or acts like it is out of gas when it is running (not fuel pump, is it the TFI module?). I am unsure what the problem is, I originally thought it was the TFI module, but the TFI module is not hot after driving around all day and it does not turn off by itself. Any thought on what the problem is or how I canfind it? Thanks a bunch!
