Question TPI stumble at WOT

When I first start my car in the morning, it runs fine. But after about a minnute or two, the car stumbles at WOT. 1987 IROC tpi 350. I have no idea. I drove the car about 100mi on a trip and when I got back is when it started hapening. Come to find out, I had 2 burn plug wires. Replaced them. Is it possible that I have more damaged wires and when the heat hits them (after about 1-2 min) that they would cause a miss?

If two wires were burnt then the plugs may have been sitting down in the gas and not firing right, they may be fouled out. Try replacing the plugs, and might as well buy a new cap and rotor too.

Nah, cap and rotor are brand new. Good call on the plugs though. I'll have to look at the plugs tomorrow. Makes sence. I rod around with the miss (bad wires) for a while.

You could aslo check your TPS, also your O2 sensors could have gone out.

You know what! Now that I think of it, you can foul a o2 sensor with a miss just like a spark plug right? I just replaced the 02 a few months ago but that could be the problem.

Sure it could. What has the O2 sensor got to do with WOT? The ECM ignores the O2 sensor at WOT so you might have other problems.

OK, turned out to be the ignition coil. But I still get a MAF ses code. Says that voltage to high. Put in another one, reads voltage to low. WTF. Also, with the voltage low MAF sensors, the car wont stay running untill the ses light comes on. Any suggestions
