Hi all. I have a 1988 Honda Accord lxi that has 390,000K. Recently had a head gasket replaced. The engine runs well with the exception of a sputter when accelerating. When the head gasket blew, I realized I need to replace /remove the Cat, so I straight piped it to the muffler ( runs better), but still the sputter. It has new plugs, plug wires, distributor, fuel filter. While driving down the road at 55-60 in 5th, it will be sputtering, then all of a sudden, it's like flipping a switch and it runs great. What could be my problem....EGR? PCV? Coil? Thanks

 

Is the CEL on? If so get the codes from the ECU under the drivers seat.

 

It's amazing how bad a car can run with a bad O2 sensor...... It's all good now!

 

Good to know you got it going again.
