Hey guys just an update, and response to paul, i just got my oem coils in and autolite 104's. i gapped them to .051 and installed the oem coils.

even after i replaced the old plugs and old coils the last time with the ebay coils the misfires were still coming on 1 and 4 during my test drive, which is about 5 miles. during about mile 3-4 the misfires would happen, cel would blink and id have to shut off car and reastart to make the engine run normally again then id get back home.

after i installed these oem coils and autolites i took it for a test drive and to my suprise i made it 10 miles and nothing came on or ran badly, on the trip back i gave it a bit of extra acceleration and it was still great but then the blinking cel came back on and engine was misfiring again with the same codes p0301 p0304, stopped turned car off turned back on and the cel light was actually gone as were the codes in my odb scanner. not sure if that is a good sign or not ut will do more tests driving tomorrow. i still have the injectors coming in and will install those when i get them to see if maybe that is it.

ALSO, is there any way i can use my multimeter to check the harness or any other way to make sure it is not my wiring harness that go to the coils and injectors? is this an actual part i can disconnect and get from a junkyard or?

you probably want to pick up some electronics contact cleaner and take the plug off all the coil packs and spray BOTH sides and then put some dielectric grease after the contract spray has completely dried.

Update!

Hey guys just installed the fuel injectors and everything is running great, and has not misfired at all, the old ones were really bad shape, orings etc and might have just been the cause. i drove an extended test drive and no misfires! i know this can be just temporary and might come back if its something else but i will keep the updates coming once i get more miles on it!
