Went to the races last night. Found out my car, when I pull all the way through the rpm range at about 6-7k it will cut out a bit. If i just run it up from 3-4 it will pull smooth all the way to 8. The car is non turbo, with streetport, 30k on the motor, 2.5" pipe with no cat, and I have the ACV and EGR block off plates. anyone know whats wrong?? something with A/F mixture???

 

Care to tell us what year your car is?

heh oops my bad, its an 86, with orange odometer numbers whoooo!

 

New spark plugs and spark plug wires?
Check TPS at WOT to make sure it's not over 6.5k-ohms.
Fuel filter relatively new?

the wires might need changing, new plugs and filter. need to check the TPS what plug to i check it from?? The test one or actually off the tps and is there 3 prongs?? which one do I check?

 

Unplug the TPS and measure resistance through green and black wires.
