I was driving to an SCCA event last night and on my way down the car started to act like it wasnt getting enough fuel but i would either throttle it more and it would pick up again but then act the same and i would have to keep doing it. Unless i put it in 4th and crusied at 4500rpm. what do you think it could be!? Fuel pump? O2 sensor? My set-up is below! Help!

I had a similar problem, dont know if it'll help

I had a ground loose on my thermostat and when i would get up to about 70 it would freak out, I dont know why it would do that at speed?

so you might take a look at it, or any other wireing that would move, thats what I did, I had my car idle and then I went under the hood and wiggled all the wires until I found it.

good luck

 

cool thanks will check it out tonight!
ANYONE ELSE?
