Well as it says my car has a stumble or miss fire in the mid rpm's from 2,000 to 3,500. This all happened afrter i broke a valve spring a couple of months ago. To make a long storry short after I got it back I broke another spring. Well now i have replaced all the springs and had the rockers all set right by my local speed shop. When they did the springs I had them put new plugs and wires on and when I got it back I replaced the Opti so I am going to assume that the ignition is not the problem. When the car starts missing I can press the pedal and nothing happens then the car pops out of this and pulls hard. The car still runs fine at WOT and runs simmilar times at the track. So my problem is at part throttle .
Could my O2 sensors have been messed up when I broke my springs?
Also could the fuel trims be off causing it to add to much or not enough fuel?
Could the fuel trims be off b/c of the broken springs?
If that was the case how do you reset the computer back to the original program?
I am about to go get new O2's but I figured i would ask you guys first.
Next step is to pick up LT1-edit or pay someone to reprogram it.:confused:
