Stumbling/Hesitation

[Silver 99 Firebird]

Hey,

My car seems to be doing what all the others are. Stumbling under accel. I've replaced the fuel filter, plugs, coils, and plug wires. The problem still remains. I managed to get it scanned and it showed a lot of misfire counts on #6 when it was hesitating. I'm gonna check the plug and wire again tomorrow to make sure everything is ok with them. If that's not it I'm guessing it's the injector. It idles smooth as always. The car is stock with the exception of some suspension mods. Any ideas on the injector??

Thanks,

David

I'm not %100 sure about your case, but my buddy is having the same problem, and it is his MAF sensor, maybe you could check it out.

Checked the plug and wire again. The Wire looked fire but the plug looked white on the electrode and matte black around the base. Changed the #6 injector and had the ICM checked. No change..I think it may be time to blow the car up.

Checked the MAF sensor and it seemed fine. Are there any problems HP tuners has when scanning our casrs. I noticed it stacked the Spark table all up into one column.

Thats not a good sign. Clean it up with a wire brush, check the gap, Put it back it. Recheck it later on and see it what it like then.
