Question about 1997 Mitsubishi Mirage
I have a Mitsubishi Mirage 1997 1.8 . I have been troubleshooting the same problem for about 1 yr now. I have a Mitsubishi Mirage 1997 1.8. This problem started back in October of 2007. First of all, I got the check engine light on my car. I thought it would be due to its yearly tune up (cleaning the injection system as well). So I thought I would take it to the auto shop within a week. Before the week came to an end, I ran out of gas and had to put fuel by using a fuel canister. After this, the car would not turn on and if it would turn on, the motor would be shaky (as if running on one ignition coil vs. two). At times, it would start as if nothing was wrong and I could drive it all day, but if I turned it off then it was trivial as to whether it would start again or do its shaky fit. So as soon as it started without a glitch, I took it to an auto shop to get the tune up I promised it and to get the belts replaced along with a new gas filter. The mechanic mentioned that they had trouble starting the car and they recommended changing the ignition coils along with the ignition switch. I chose not to do anything further and took the car home. A buddy of mine helped me out a bit and we verified that the fuel pressure was at its recommended level, and we also checked to see if all the injectors were passing fuel. They checked ok but we also saw that only one ignition coil was firing. I took the car to AutoZone to get it coded and it came back with a misfire detected and a camshaft sensor problem. I read about the camshaft sensor symptoms on your earlier Q/A and they matched exactly what I was going thru. I ordered a camshaft sensor and bought the Chilton book for my car. I replaced the sensor and WOW; it fixed the problem…but only for 1 week before the car started getting shaky (especially when the motor is warm). I took the car back to AutoZone and got code PO340 “The PCM determined a malfunction exists in the electrical circuit for the camshaft position sensor A”. Does my car have 2 camshaft position sensors? (one inside the timing belt housing and another on the driver side of the motor near the crankshaft? Is this problem related to the dreaded PCM problem that I have read so much about on my type of car? I checked the wiring to the camshaft position sensor and I do not see any tears or frayed wires. I can only look so far at the wiring because they all go into some thick tubing. A couple of months ago, I replaced the ECU Computer (the one by the glove compartment)I have also cleaned all the connectors that I could physically get my hands on and to this day, the car starts shaky. Any help will be greatly appreciated on what seems to be a lost cause.
