What the F*#K is wrong with my e30??

Had the same issue once. Never figured it out. Try running Seafoam in the gas tank. Maybe the fuel got contaminate with water. Might not help but wouldn't hurt either.

Hey guys. I have not figured it out yet. However I promise to update this thread when I've resolved it so it can be used for future trouble shooting.

I had a split second stutter under load too and I will say with 90% certainty that it was cause by old hoses on my car. Crank vent hose that runs under the intake manifold was in pieces. And the fuel breather hose connected to the bottom of the throttle body was also in pieces.

Made some progress. Installed new spark plugs and eliminated the lower RPM stutter. Still getting the sputter at WOT though. Even if the throttle is at 95% I don't get the sputter. Pretty weird. Also decided to buy a new Bosch coil and nothing.
