I installed a Racetronix kit a few months back, drove the car to my dads and parked it there for a few weeks while I moved. The car ran GREAT on the way over there, no problems at all.

I go to pick up the car and on my way home, the car is bogging really bad when I give it even 1/2 throttle. Not sure what would cause the car to run good one second, start the car 2 weeks later and it runs like crap. Any ideas?

The only difference between days, the day it ran good it was 30 degrees warmer. But I doubt that would have any real effect.

Thanks,
Jason

 

Did you check the tank for rust and replace the fuel filter?
Check you fuel pressure while driving.

 

There was no rust in the tank, and I have not changed the fuel filter yet. I will do that this weekend. The reason I didn't bust a move for the fuel filter change was cause the one in it, only had like 7k miles.

I'll also pick up a fuel pressure checker thing so I can see it while I'm driving to see what it's doing. I probably need one anyway really.

Thanks for the help!
