Hey, 4g15 gurus...help needed .

My new summit has an unfortunate miss at low rpms (I think it is low rpms...no tach). Get on the throttle even a little bit and *bup* *buuup* *buuuBruuum*. It has new plugs, cap, rotor, oilchange, airfilter...should get new wires soon. If I can get around to it, the fuel filter is getting changed too...what does that leave as a possible problem?

I am going to check my codes tomorrow, but does anyone have any possible tips to where I could check first? Coolant temp sensor (it is real rich at warmup), TPS, etc?

Want to just skip fixing it and buy my old engine?

As for the miss, I'm not sure what causes it but my girlfriends car does the exact same type of thing (I think.. judging by your description). She has a 99 daewoo though. (avoid daewoo cars like the plague)

I sure know I'm gunna keep a close eye on this thread.

prolly ur fuel filter needs changing..injectors could be a little dirty....or at worst ur computer is about to take a crap...mine did the same thing..it sputtered around, check engine light came on..and 30 min later it died...
