EA running like a Dog
I have a 89 EA Wagon with a 3.9CFI with a 3spd box. I have been nursing it along, because in the next year I will be swapping it over for a 4.0, since it has low compression and a rear main going out.
The current problem is, that when you hit it hard it falters and then blows a puff of black smoke and takes off. But on a few ocaasions it has hesitated, bakefires and died. No a good thing to be happening when the wife is driving with the 3 kiddies are in it. It idles as pretty as you please.
I have changed the leads, plugs, dizzy cap and rotor, followed by the thermostat(170 degree). Removed the injectors and had them cleaned. Changed the coolant temperature sensor and idle control motor. Changed the MAP sensor and fuel filter and fuel pump. The air filter is clean, and the exhaust is not blocked.
Any suggestions, I have had to a few mechanics and it keeps coming back unchanged after a short time. I am tired of spending money on it since I will be yanking it out soon.
