1997 Tahoe misfire without a code

[bubcol]

I have a 97 Hoe LT, it misses when I accelerate from red lights and stop signs, but clears up on the highway, does anyone know what this problem could be? Already replaced the Distributor cap, rotor, coil, ignition control module, plugs, and wires, and it is not throwing a trouble code!

Be sure to use plenty of Dielectric grease when doing a tune up.

You could maybe have a EGR problem,slight vaccume leak,coil pack issue,or one of the spark plugs was damaged or the gap was messed up during installation.

Or it could be as simple as getting some bad gas.You could have got gas from somewere were you normally don't get gas from and now you have an issue.
