Engine Performance problem
1989 Honda Prelude 4 cyl Two Wheel Drive Automatic 185000 miles
I replaced some coolant hoses under the intake manifold and when I put everything back together, it ran rough and would almost stall when I gave it gas while in gear. I rechecked everything and checked timing. Everything looked good but I got codes 2, 5, 12. The oxygen sensor code was already there. 5 is for the MAP sensor and the 12 is for the EGR. The Map sensor checked out as good. The voltage for it called for 3 volts and read out at 2.75 volts. I got a different ECU to see if that is the issue. The ECU I have may be for a stick rather than an automatic. The number is 37700-PKI-661. The engine runs so rich it is fouling my plugs. Runs smoother warm but still too rich and blowing dark smoke out the exhaust.
have the same problem?
