Misfiring problem?

[JayRolla]

Ok whats happening to my car is wierd. Most of the time it runs great but sometimes ill be cruising and all of a sudden it starts to bog like its misfiring. If im in neutral and let the rpm's drop it causes my car to stall. If im in neutral at a light it will bog and the cel comes on but as soon as i rev the motor it goes away. It only happens about once a week. When ever it happens all I have to do is hit the gas a little and it goes away. I used palm o stein to read the codes and a bad crank angle sensor pops up. If I use MMCD it has no codes. Could the crank angle sensor cause this to happen?

Yes, I believe the crank angle sensor could cause this. If the sensor isn't reading anything, then it wouldn't know what's going on and it'd just crap out and die. Maybe try a new sensor. You have a 91, so a new cam sensor would probably do the ticket. They're relatively cheap and very easy to install. Maybe check the wiring first for shorts and such.

So since im a 91 your saying I dont have a Crank angle sensor just the cam angle sensor. Im confused because the ecu code says crank angle sensor not cam angle sensor. Do I have both or just the cam angle sensor?

The cam angle sensor reads the cam angle and crank angle. It's one sensor that does 2 things. On 95-96 cars, they have two different sensors. My point is, it is that sensor which is probably faulty and new ones are usually like 20-40 bucks to get from someone. Search the classifieds or ebay.
