1999 Honda civic d16 non vtec sounds like running on 3 cylinders I bought this car from a couple of kids who wanted some quick cash, its a dirt track car that their father had built for them and they had cut the harness going to the abs stuff and removed those boxes. I thought it could be something simple so ive replaced the distributor cap-plugs-plug wires. haven't gone much further planning on doing a obd1 swap as well. just curious what I can do to fix it now to make it run right again....considering to change fuel filter ect. the computer in this car I gave to them out of one of my old dirt cars that made it run horrible to begin with in my own car could it still be this computer causing the issue or what do I need to check????

 

Is the CEL on? Does it work? What color is the spark at all four plugs? Have you done a compression test?

 

good compression and the cel doesn't excist in this car being as the stock panel is removed. I haven't checked plugs since changing them over to new ones this afternoon

 

Please don't waste our time. Give full and complete answers.

"Good compression" means nothing. Exactly what are the numbers for each cylinder?
I'll ask again, what color is the spark at all four plugs?
And since I guess you missed it the last time, I'll reiterate what RonJ told you over 5 months ago.

 

holds 140 psi on all 4 across. may of found the issue being as the ecm I installed is a p2p witch is vtec ecm where this car needed a p2e. was told that this will cause this issue..
