Just got my first dsm it's a 91 laser 1.8 nt. I'm having an issue with it stumbling when I'm accelerating, there is a sweet spot on at about 1/2 throttle that it doesn't stumble. At idle i can rev it and got wot with no problems. Here is what I have done so far. I dropped the tank replaced the fuel pump, and strainer, new fuel filter, plugs, plug wires, air filter l, checked it over throughly for vac leaks found none. MAF is good injectors were pulled and cleaned fuel pressure checked out, new O2 sensor, and the exhaust is not blocked up. The only thing I can even think to do as of now would be to check the TPS, but would that cause hesitation and stumble only under load?
