I currently have an 86 with 197,000 miles on it and it died about 2 weeks ago. I have been following advice from the faq page and got it to run again. It ran horribly and thus followed more advice and got it to run better then went bad again. Long story short engine is no good looking for another. I found a 1990 with ecu and wiring harness will this work in my car? Or can I pull stuff off of old block to work on this block?
