Every time i make a WOT run, the next time i start the car it has trouble starting. It starts right up everytime, except when i make a "hard run."

have a new fuel filter about 10k ago, FWIW

 

you mean no matter how else you drive it while the car is on, if you happen to go wot once, the next time you start the car, then it is hard to start?

 

hmm that is weird, MAF is first that would come to my mind, or maybe something with the TB, prob IAC related...just guesses though

 

i know it sounds strange, but it does do it.
Exactly. I can start five seconds after the run, or five hours after, always the same. Normal driving then it wont do it.

All i can think of is crap is running around the opti and gets stirred up, or the coil is taking a crap on me. When i start it after the WOT throttle runs it will not be a total loss to start, it will take about one second more to start. It is not just coincidence. I guess i will just start replacing stuff.

 

I had a problem with hard starting and it was my fuel pressure regulator. Pull the vacum line off it and see if you smell gas.
