A bad ignition coil is probably not the culprit, it would likely do it at more than one speed if it were a misfire caused by a coil. It is hard to say without actually driving the vehicle. It could be as simple as a wheel out of balance or a defective tire.

I would start by trying to isolate if it is engine vibration or something in the suspension or wheels. Once that is done it would be easier to diagnose it further.

Generally a front end shakes at that mileage is do to tires needing balanced especially if it stops when you go over 50 or more

    I would have the tires checked and if they are in good condition then have them rotated and balanced.

I havve a 95 bonneville.. 3.8 under acceleration the engine shakes. there is a slight loss of power. but when the rpms are up to say1800 the shake stops. it also shakes when passing. what causes this?


It sounds like you may have one coil pack dropping out. If you mark and remove all of the plug wires at the coils, then have an assistant crank the engine briefly, the coil that has no spark, or poor spark between the towers would be the culprit. Switch it around with another coil. (usually the hold down bolts are 5.5 mm) If the problem follows the coil, it's a bad coil. I f the problem remains in the same position, you have a bad transistor in the mudule and the module will need to be replaced. Good luck, and contact me if this is not the problem, or if you need frthur assistance.

1993 Pontiac Bonneville will idle only


Wait, first check the fuel pump, fuel filter and the ignition coils. If your fuel pump goes bad, it will start to heat up a lot and **** the voltage from your alternator, indirectly lower your battery voltage and can also be linked to coil failure. It will act up more when there is less than 1/4 gas in the tank. you can check the coils by getting a new or used coil and using the process of elimination (very rarely do all 3 go bad, if your car finally turns on and shakes so much that it feels as if will turn off but never does and your voltage goes way down then its at least 1 of your coils). The fuel filter should be changed if it hasn't been changed in the last year ( I recommend it for these cars as bad gas causes much damage) and check to see if fuel is getting to your engine. These cars also have fuel leaks around the front of the car especially where the 2 metal fuel lines meet under the front passenger side (the rubber connector wears out). If you're fuel pump is bad I then recommend changing your fuel pump relay as voltage and pressure will adjust. I hope this helps. Good luck

1993 pontiac bonneville sometimes wont crank and stales out


Check the ignition module. The coils plug directly on to it, it should be silver in color and about 1/4-1/2" thick.

1993 jeep grand cherokee *shaking VERY BAD in front end*


I have driven one that does this! When it does it, you can barely keep it on the road! Jeep calls this DEATH WOBBLE. Google it to learn more. I fixed the one I worked on by replacing the front tires. The tires I took off didn't look like they had a darn thing wrong with them. But when I put the Full size spare on the Left Front, the problem was gone. We also replace the steering stabilizer, shocks and tie rods on it too, but did nothing to the problem. After the customer replaced the tires, the problem has not came back. This was three years ago.
