Everything is fine until I drive 70 mph. Then the car shutters and the the gas pedal doesnt work until I come to a complete stop. Then Everything is fine again. Any ideas?

 

so, you plan us to help, but you don't give us any info to go off of. We need to know what year, make model, what engine and tranny it is. What mods are done, what ecu are you using. Every bit of info is critical.

 

Im so sorry I forgot. Its a stock 1997 civic with an automatic transmission. D16y7 I think.
