Hi, I have a 1990 Oldsmobile Cutlass Calais with a 2.3L 4 cyclinder and about 64,000 miles. about a month ago the car started shaking really bad and had no acceleration. And then i was driving and it started shaking really bad so i slowed down and then it just shut of. So i ran the codes and it said it was the OXYGEN SENSOR. So i replaced that and it still shakes. So then someone told be to replace all the spark plugs cause maybe it was miss firing so i did that . But today it started shaking and had no acceleration and shut off completely again. It doesn't always shake. It seems that about every other time i start the car it shakes and has no acceleration. But if it is shaking and i hammer the gas pedal and sometimes comes out of the shaking and acceleration problem. Could it possibly be some kind of electrical problem?? Timing?? Any input would be very helpful. Please help!!

Devin; Referencing your nearly identical post of Feb.14th; Have you checked the firing order to make sure that you didn't get a couple of plug wires crossed? You noted that if you 'hammer' the throttle it will sometimes, come out of the shaking and accel problem. If this is the case, the wires are probably correctly connected, but one or more could be bad. Also, could be a coil problem. Also, could be an injector problem. Get the picture? You need to get this diagnosed. You can buy a spark tester and start checking each, individual coil/wire, but the problem is going to have to be there to find it that way. You can buy/borrow/rent an ohmmeter and check resistance in the wires and primary windings in each coil. Or, pay a shop to diagnose it for you. You can still do the repairs yourself, once it is diagnosed. You may want to go back and review the posts and replies from Feb. 14 and Mar. 1.
