Engine Performance problem
1991 Honda Accord 4 cyl Automatic 175000 miles
We are trying to repair a 91 Honda Accord for our friend and are having problems. He said at 1st he had problems with loss of power while driving, it seemed to him that it was not getting fuel (or much of it) and he couldnt get it to go over 30 mph. Then it just quit starting all together. We found a clogged air filter and plugs with lots of carbon deposits as well as a burnt spot on the rotor. Replaced these things as well as dist cap and the car starts and runs. After running maybe 30 seconds to a minute the engine revs slightly and then idles poorly, at this time the check engine light comes on. We checked for codes and it gives a 4 blink sequence which indicates "crank angle." I have found thru some online research that there is a crank angle sensor inside the distributor. Does this mean the distributor is bad? Also we noticed low oil, we added some and now suddently the check engine does not light. It ran for a few mins just fine. Another problem is that there is a knocking noise coming from the area of the valve cover. Friend says the noise was not there before he started having problems. Any idea about what to check for the "crank angle" code, and what the knocking noise could be. Is this kind of noise coming from this area considered a "spark knock"?
have the same problem?
