I used the seach engine in hopes to find the answer to my problem, but I was unable to. So here it goes:
I just bought a 1991 integra ls. The folks I bought it from said they changed the timing belt, water pump, and distributor.
First off, the car idles high when first starting and fluctuates from 500-800 rpm AFTER accelerating. I changed fuel filter, cleaned throttle body, IACV, FITV, and air filter. Alas, same problem: crap acceleration and bad idle.
My current situation: I am UNABLE to adjust ignition timing to 16 degrees BTDC. I allowed the engine to warm to operating temperature, jumped the service check connector, then used a timing light to check ignition timing (I got the idle to stay around 750 rpm). I advance the distributor AS FAR AS IT CAN GO, but the ignition timing is still several degrees after TDC. I removed the #1 spark plug and with a pressure gauge, set #1 piston to TDC on compression stroke. Then I checked the rotor on the distributor and it is making contact with #1 plug wire(excuse my ignorance, I am somewhat new with this)., at least it appears to be making contact from the angle i can see it at. So it seems to me that if my TDC notch on the crank pulley points to the mark on the front end cover AND my distributor rotor is pointing to the #1 spark plug, then My timing SHOULD be good, right?
So basically, timing slowly goes from, lets say, 40 degrees BTDC when first starting, then goes after TDC several degrees as the car warms up and reaches normal idle(well, as normal as I can get it).
I am totally stumped.Someone please give me a list of things I need to check BEFORE i visually inspect crank/cam sprocket alignment. I would GREATLY appreciate ANY help. Thanks.
