1993 Mazda MX-6 ProblemsMisfires Under Load
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.
Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.
If the engine cranks but will not start, it may be due a failed distributor. In the diagnosis, it may be discovered that the Electronic Engine Control (EEC) Unit is the cause if ignition spark is restored after disconnecting the Spark Output (SPOUT) Connector.
1993 Mazda MX-6 QuestionsWhy would transmission & tac do a major shift down reducing speed below 50 mph? (1 answer)
Original engine (300K). 2 yr old transmission (ck'd out ok). New ECC. New distributor. "Strange": If I turned on lights (which showed a power-down on idle), I could then drive car and not have problem with transmission and tac (shifting down).
Runs good most time. But when pulling is enforced, it always kicks outta 5th even as I hold the gear shift in. I just had clutch replaced around 2 years ago so I know that's not the prob.
Even though the defroster works I have to continuously wipe off the fog on all the windows. I see no leaks in the vehicle. This has become a safety problem.
