I have a 91 hatchback 2.3 EEC IV, auto trans with 286,000 miles on it. Last month I noticed a problem with my tach and loss of power (like there's a whole lot to begin with) :Þ
The tach would register ½ of the actual rpm's, the engine would run rough and there's a definite power loss. Eventhough the tach would say 500 rpm's, the engine is still going at 1000, but rough running and I can hear a chugging of sorts out of the exhaust. Both coils are firing at the same voltages when it happens or when it doesn't. I did the wiggle test on all sensors, modules and cleaned all the connections but it doesn't change anything and still randomly occurs while idling, moving, full throttle, ½ throttle, whatever. There's no set weather or temperature occurances for when it happens and could be days, weeks, or minutes between them.
The code that popped up was an erratic P.I.P. (code 14)(Crank Sensor) and igintion coil 1,2,3 or 4 (code 224)circuit failure. I replaced both coils and condensors and the crank sensor and it still randomly happens. In case I got a bad C.S., I exchanged it for another and the same thing happens. The PIP code no longer pops up, but the coil code 224 does when this happens. When this happens I've pulled the rear off and it runs even rougher, pulled the front one off and very little change. When the car is running smooth and I do it, it's the same.
Any insights would be great HEEELLLLPPPP
FYI I have done several mods to it, but well before this started happening. The mods I did are as follows: Custom header with performance exhaust, capped off EGR, IAT "chip", accel supercoils, C.A.I.. The coils were done after this started, but the others well before this.
Again-any help would be great- Thanks-Jeff
