Engine Performance problem
1990 Honda CRX 4 cyl Front Wheel Drive Manual 200000 miles
I recently did a dpfi to mpfi, I changed the wiring over, put in a pm6 ecu, a crx si intake with fuel injection, resistor box. The ecu throws no codes.
It idels at 1k and is smooth through the rpm range up to 7.5k If being driven and I mash down on it it runs smooth, no signs of missing or backfires. At high rpm and shifting gears it jerks and seems to loose power for a few seconds and then catches back up.
It has new wires, new cap rotor, new distributor, new plugs, and a new timing belt. I ran a bottle of injector cleaner through the gas thinking it was a clog in the injectors but no result change.
I was leaning towards its off time by a mark or so but im not sure. The distributor is ajusted to be at the highest point so it idles a little higher then if I were to push it back to its lowest point and get a idle of around 800
any ideas. IT would be most appreciated
have the same problem?
