about 11 months ago i started this build after i had blown a head gasket. while i was preparing to take it all apart to replace this gasket, i started think to why dont i just pull a little more money and build this motor. well thinking and stressing went by pretty quick and i decided to build it and also replace gaskets of course...
heres the breakdown of this motor. i went with .020 bore, je pistons and rings, manley rods, arp 2000 bolts and crank was grinded down 20th(i think thats how you would say it), and also oversized bearing to fit. also longtubes, x pipe catless, ported heads. had the intake valves replaced on the passenger side head because of a mechanics mistake. had a machine shop build the bottom end. got the bottom end back and i started my put together process. everything went crazy after i needed bolt here, grease there, ect.. all said and done it was finally finished.
about two weeks ago i was gonna start it for the first time but, i had no spark or no fuel. i checked my cut off switch checked my wires and eventually found the crank sensor and cam sensor wires stripped and touching. well i fix those problems the motor started right up and ran healthy and strong. there was no misfire, no fuel issues, no problems what so ever. it idled great and then i decided to change my spark plugs to good new ones. did that and still ran fine. i couldnt drive it because i need to register it and smog. i went to the dmv and got it temp registration. drove it for the first time and i started to have a slight misfire at idle and a really bad misfire with a slight load on it.
ive got a predator so i set my rev to 3000k to be sure i break it in properly. on my drive i never went over 3k or 55mph. brought it home and tried to figure why the hell the problem is and this is where i am.
on the driver side ingnition wires for cop i took of eletric tape and found a short in the wire. fixed that and it helped but didnt eleminate problem. went through all cylinders and pulled cop out and found a cylinder that would have no affect of idle with me pulling it out completly which is #1 cylinder. im getting spark to coil but its kinda irregular. kinda like a heart would act if it had a heart mumor. i thought maybe it could be sparking to wall and not spark plug so i taped all cops with eletrical tape. no fix... my tps was out fixed that and it didnt fix the misfire. checked all wires around the cylinder and even fuel injector was replaced thinking it was that.
when i bought this car is was a 99 cobra with 99 cobra stock motor. it had 165k on it. motor blew and i put in a 04 mach1 motor and 3650 trans. i kept the 99 cobra wire harness and ecu. could that be a issue? im so stumped right now. could i have dammaged the pcm or anything of that order? im getting so frustruated with this issue im getting closer and closer to taking to the dealer. or sell it.
please, any help or suggestions will be gladly appriciated.
