I have a 1992 Honda Accord EX 4 dr. The check engine light comes on after getting out on the highway and driving at 55 mph +. Also the engine idle runs really low when at stop lights, in drive gear with brake pedal pressed the rpm needle fluxuates down to .5 rpm then up just above the 1. There is a strong exhaust emission, rich fumes etc. as well. Anyone that can diagnose possible solutions?

 

You may want to check your engine timing first. Get a timing light and perform any vacuum plugs as directed on you veci label- found under the hood. I think the timing is around 12 degrees before TDC. Get a Hayes manual to verify this info.

 

Do you drive an auto or manual?

 

1. pull the code and find out what is wrong.....
2. post your CEL.

 

the car is telling you whats wrong, you just need to ask it for the information.

pull the CEL code.
