I have a 1994 bonneville, with the series 1 L27. Im looking for some performance options, because I find after 4500 rpm the car starts to run out of breath. The car is absolutely stock. It has the 4T60e transmission.

Also, can you please tell me how to change the spark plugs behind the bank? I find it hard. Im only 16 and im no absolute genius at removing motor mounts. Any help would be greatly appreciated.

Thanks!

You should be able to pull them out fine without tipping the motor. It'* very possbile. I didn't change my plugs, the shop did it cause i had it in for other work. I did my wires though, and my 02 sensor. Just get a mirror, and a socket wrench and extension.

why woul du want to drop the motor to change the plugs it isnt that tight. it isnt hard

Use the strut tower brace (the big black bar that runs across the engine) to lay on (from the left side of the car looking at it from the back, oppose teh master cylinder) and to get leverage with. Then you should be able to reach and pull of the plug wires and with the extension get the plugs.. JUST BE CAREFUL when you reinstall them. Screw them on with the socket and your fingers (no wrench attached yet) first to make sure you dont cross thread the holes. then leaving the socket on the plug, attach the wrench and snug them up... hope that helps

Welcome to the club!! I was just about to mention the swivel. Or the one that'* like a u-joint?? What'* that called?? My mind is blank today...
