Engine Performance problem
1990 Honda Accord 4 cyl Front Wheel Drive Automatic 287, 00 miles
What causes Co% (max.63 Measured 1.57%) to be too high in only the 25 MPH Test?
Before this we had to replace the EGR Valve and reset timing from 8 degrees (BTDC) to 15 degrees (BTDC).
Since the test, I also found the Cap and Rotor was bad, so I replaced them, as well as the Plugs (Fair Condition), Air Filter (Fairly Dirty), PVC Valve, and it had an Oil change recently though the car sat a couple of months.
All other test scores are fine.
have the same problem?
