Missing/Hesitating while accelerating.

[TurboAWDKID]

I have a 1990 TSi AWD Talon and when I start going it hesitates, like it is not getting enough gas. I noticed this after I put Gum Out fuel system cleaner in it. I think the spark plugs or fuel injectors are dirty or clogged. I just recently put in fuel injector cleaner and a higher grade fuel system cleaner (STP) and it seems to be running a little better, but not much. I also thought it could be the fuel pump, which in that case i was going to just upgrade to a high performance pump so then I am set for a future turbo upgrade. I don't know if this is a common prob with DSM's or not, so please give me any info you guys might have on this. Thanks.

Stop running that crap through your engine, and replace your plugs and wires. BPR6ES at .028", and anyone's "upgraded" wires.
