[slamingears]

hey, here is the prob, i have a 90 talon turbo, wene im driving and holding it at a steady idle it starts to miss, wene it startes to miss i give it full throttle and it misses till about 3500 t0 4000 rpm it and then the miss goes away, wene its just idleing u can here the miss and its a little shaky. sometimes it does it so bad i cant drive the car unless im in the boost the whole time. so i went ahead and changed the plugs (ngk) and wires also changed the coil pack ### it was the factory one also changed the fuel pump (bbk 190) and fuel filter last summer. car is preety much stock except exhaust and cold air. iv looked threw all the forums i could and i didnt see any with the same prob as mine please help thanks guys

What did you gap your spark plugs to? I gapped mine and it went away.

check your timming marks...the timming will not advance untill you are under power.

I hate to ask obvious questions but did you try to clean out the area where the spark plugs go in, I had the tiniest bit of water in mine and it caused the same problem. Also make sure the spark plugs are good, there always that chance that there not, or possibly gapped improperly. Hope this helps!
