okay so my ef has a d15b2 block with a z6 head, obd0 to obd1 conversion harness and chipped p28 ecu my harness is wired by a shop, it took me a while to get it running but when i did it ran great vtec engaged and everything but the past couple days i have been messing with it and it doesnt idle, its running on 3 cylinders and dumping gas out the exhaust, ive been told its the timing or i need to advance my dizzy blah blah anyways i would like some help, anything i havent tried is worth it thanks

 

Running on 3 cylinders doesn't sound like a timing issue.
Sounds like you need to get the 4th cylinder firing.

Anyway, what were you doing to it when you were messing with it?
Just undo what you did to it. Apparently it ran fine before you touched it.
