Engine Performance problem
2001 Saturn SL1 4 cyl Two Wheel Drive Automatic 172000 miles
I was hoping you could help me out. I am having a problem right now I can't figure out. Maybe you can give me an idea. I will describe as best as possible since I have never come across this. First off you need to know that this is a 2001 Saturn SL1 1.0 SOHC.
The last week when I accelerate sometimes the car shakes a little. Its pretty sporatic. Only happens once in a while. Now the Check engine light is on so I went to the nearest auto zone and they did a computer run on it. Came back Camshaft Positioning Sensor which the car does not have, but has a crankshaft position sensor, same thing so I replaced it. Seemed to work for a short time but started up again. Took back still shows position sensor bad? Maybe plug. Just got another plug today to put on but havent done it yet. Also checked and re-gapped my spark plugs and checked the plug wires all is well. When I put the car to an idle it does not quit, does not act like it will quit. Not acting like its chugging for gas just vibrates a little. Could it be the crank sensor plug? The code said it could be timing off, but I cant find where there would be a timing belt and I cant even find a part online so I dont know if the car has that or not. All I know is that the transmission shifts fine so its not like gears are messed up there and it does not shake hard. Tomorrow I will probably replace the plug for the hell of it. Tires have no bulges in them so it cant be that and I even know if there was a bulge it would be all the time. I just never seen this before and I want to make sure its fixed and safe for my daughter to be in. Winter is near and I dont want a dead car. Please if you have ideas I havent thought of please let me know. I am in no way a mechanic but I do do most of my work when I can so hopefully its easy. Also I forgot to mention that on the codes it said cam sensor bank 1. Is there more than one crank sensor in a car or no the bank one threw me off. Thanks again I hope you can help
have the same problem?
