1994 Pontiac Bonneville 3800 non supercharge?

what everyone else said. go bonnevilles

Yeah, it'll directly bolt in. You'll need a new ECU though, and if you're looking to make your series II faster, why not just shorten the pulley, get exhaust, and headers? It'll save you a lot of money and a lot of work.

Must be electrical and / or heat related. A vapor lock in the fuel line, gas cap loose or needs filter changed?

that could be a bunch of things, I'll start with a tune up, but then again it might be your computer going out, make sure there is no trash shuved up under your seat overheating the computer, if it is there, if not, try your ignition switch too they are famouse for GM around that year. if anything else you need to get a diagnostic test done on it when it does it.

this is most likely a problem with your cars computer. I'd take it to pontiac and have them install a new ECU. Regardless of the cause, take it to a garage and have it throughly looked at.

If its a hot day, your car bay be vapor locking or your ECU is getting hot and needs replacement. Sell it and get a smaller better gas efficient car.

Im willing to bet its the BCM (body control module) try locking the driver door and close it then unlock it with the key that should reset the BCM. if not then try the crank sensor. i had a cavy that did that.

crank sensor(common for wires to sensor oil soaked) or harness at ign module for poor terminal tension.

Could be a coil pack, or a crank sensor.........Make sure that you stick with OEM parts for this one.
