I Have a 90 accord with a 99 CL motor, did some wiring changes and engine runs and goes, But it eats gas and the idle goes up and down between 2 and 3 thousand RPMs, put it in drive (auto) and it rocks the car until you turn on the A/C then the idle in steady, as i drive it's fine until i reaches where you're not giving any more gas but trying to stal at one speed, the RPM's go up and down. My friend tells me i need a new computer ( Yes I am using the 90 accord (ODB0) with that motor) and thats why its doing this. If he is right i think it's because where the TDC and CNK sensors are in different locations(90Distributor---99Crank) whould that be a problem? and if this is true then all i need is an ECU that nhas it's sensor @ the Crank? Isn't the ECU for emmisions and diagnostics? If i do need a computer which one ?
