alright last week i was driving and i came back home to put my dvd screen in my car so i get done with that and such...go to start my car andf batt light comes on so i'm like aight check conenctions n such...we it ended up being a burnt wire off from the alternator termical the copper had pretty much turned to powder...so i go to start the car again and all is well....then it started missing n such at idle...went to go drive it it shakes while accelerating and it's like not going anywhere..then i punched it and it was fine then...went to go punch it again and....same shutter problem. the car is undriveable. i checked spark plugs and they were all good. what happened was the weld on the tubular manifold cracked a hair and it charred the #1 spark wire so i replaced that and ohm checked the rest all is good. brand new cap and rotor. at idle i go to pull the IACV and nothing changes....isn't it supposed to idle up... i gotta get ahold of my buddy so i can borrow his mac scanner. will this IACV show up on codes. any places to look for prone vacuum leaks? i did a quick visual and the the hoses look fine and the engine builds boost and the spark off the wires is blue. i started the car at night and i didn't see any spark jumping across the wires at all. and now when it's warm it idles fine at 1k, but before after about a min after it was warmed up it would chug on itself to keep alive and then the engine would catch itself and rev to like 2 grand and then back down to 1k and it would be fine for acouple of minutes and the engine would do the same thing. any ideas gurus?
