Question about 1989 Honda Accord 4 Door

1 Answer


I have an 89 honda accord that backfires and stumbles when the automatic transmission shifts. A hose that connects the air control valve B and the anti afterburn valve to the carb blows off if you accelerate quickly. It doesn't blow off if you accelerate gently but it still stumbles. Can anyone help.

    Car has already been tuned up, timing belt was changed, carb was changed. The mileage is 184,000 but has good compression and their is no leakeage around the head valves. Their was a broken vac hose on the egr but I fixed that and the problem still exists. When it backfires it is running fine and as the trans completes its shift then there is only one backfire and stumble untill the next shift. If the car is in park the car revs fine and does not stumble or backfire. Only problem is just after shift point.

Does the ECM control the automatic transmission or the shifting pattern?

Probably not the ecm.. look for bad plug wires, vacuum leaks, timing settings, Crank Position sensor, Spark plug wires incorrectly installed, Try this.. Open the hood at night and look for the plug wires leaking.. you are looking for sparks.. I would look for disconnected Vac. hoses, broken or cracked vac hoses, ..

I have a 91 honda accord with an automatic trans. & when i shift into reverse it refuses to engage & makes a high pitch gear slipping grinding sound ! NOT GOOD ! ,I just replaced the transmission con

Definitely not good. The transmission is slipping internally due to worn gears and clutch packs. It will have to come out for rebuilding, IMO. Have a transmission shop check it out.
