On Sunday I bought and replace # 2 injector, clear the code, run around block couple time, now I still have P0302 and new one P1351 = Ignition diagnostic monitor circuit input fault. what cause P1351?

 

Today I put back the old original ICM (because I think it still good, I replaced it by guessing) and it clear P1351 (hope it don't come back), clear the code, drive around a block couple time, then scan again, I still have P0302, I though I replace # 2 Injector (and Plug, plug cable) it should take care of P0302? but it not. So I might still have problem with # 2 cyl? but if it missing only # 2 it should not be that bad, at idle it misfire, (seem like more then 1 cyl), when driving step on gas it stumbles, stutter, then driving around 10 to 20 mph then it shoots up to 30 to 40 mph. Almost as if something was stuck in the airflow or something was restricting the system?

 

I still working on my truck, not giving up yet. I still have P0302, I did replace # 2 Injector, plugs, cable, coil, ICM module, compresion good. It idle rough(seem like missfire more then 1 cyl), when driving step on gas it stumbles, stutter?

 

I still working on my truck and still have problem. I have P0300. It idle rough, when driving step on gas it stumbles, stutter bettwen 15 to 25? it get better 25 to 70 but still feel misfire?

On my 98 i have had to replace the cap twice so far because the #2 and #8 cylinder points shorted out, maybe on yours it just shorted out the #2, i know you said you replaced the cap, but it isn't that hard to check, it will show on the inside of the cap with a littel crack and corosion

 

Thanks wffokker, I will try the cap. Currently I have P0302 (yes, it change from P0300 to P0302, that make me more confuse and lost) It idle rough, when driving step on gas it stumbles, stutter bettwen 15 to 25. Yep, I not give up yet, I'll will fix it some day.
