The car is a 90 XR-7, auto
First the symptoms and then what I have tried.
Engine misfires, could be that it is not firing a few cylinders.
Comes and goes.
Tachometer goes dead.
Stop car, shut off, restart and it runs normally.
Tachometer does not always come back to life.
Starter started acting up on me, so I replaced it with a rebuilt.
Starter lasted two days, it tested bad, so I got another on warranty.
Sometimes it will spin normally,but not start.
Sometimes it spins normally for a few seconds, than groans like a dead battery. Switching it off, then restarting, it spins normally. Sometimes 5-6 tires to get it to start. Sometimes it starts right up.
This happened tonight while I had the lights on, while spinning normally lights did not dim. When it started to groan, lights dimmed. Let the key go, tried again, spun normally and lights didn't dim. Also didn't start until 6th try.
What I have done.
Since the misfiring/not firing was a problem I had before I replaced the year old ignition module. Local store could not test module, so I got a new ignition module on warranty. Doesn't seem to be any different.
Replaced starter and fender wall solenoid.
I have a new ignition switch, but haven't put it in yet.
Since I replaced the starter, the misfiring has gotten worse. I had it before, but it was only every week or so. Now, it happens 2-3 times a day.
Anybody see any connection between the two? Any guesses?
