1 coil no spark 91 SL
help pls.I drive a 91 sl manual 112,000 miles. i dont know anything about cars.
when i start the car during morning the rpm is at 2000 and it idles fine. after 5mins the rpm goes less than 750 and the engine chokes and idles bad, engine light is on . its drivable biut there is no power in the car. but sometimes the power will comeback.
i took it to a shop and the mechanic told showed me there was no spark in 1 of the coil and he said that might be the problem. I am hoping it is a coil problem because i have read in the forums that it might be a cam sensor or ECU too. how do you know if it is a cam sensor problem. what could be the problem causing to my car. can anybody pls help me thanks.
also how much is the labor to replace the cam sensor and why is the 1st gen cam sensor $400?
how much is the labor to change one of the coils.
