95 Bonnie fire or fuel...I say fuel
New 2 the board here....
I have a 95 bonnie that had a constant miss I think...I think rather than firing problem it may be fuel...I can hold the accelerator to the floor in park and the rpm'* go up to 3500 and drop repeatedly like I was racing motor with my foot over and over....Fuel pump going out or clogged fuel filter?
BTW, what would the injectors act like if I had water in my fuel? I had a problem with my chopper which was water in fuel related...Bought gas at the same store....Ran the tank on bonnie nearly empty yesterday before I filled up at another store, then the problem started soon after...I think I may have stirred up the water since it settles to the bottom... :?

How does the car perform when you're driving it? If the RPMs only go to 3500 in park, the you're simply hitting the rev limiter. You should never free-rev the car like that. It'* the worst thing you can do to it. In my opinion, the rev limiter should be set at 2000 RPMs.

hmm
Didn't know they had rev limiters...ANYWAY,
It misses at idle and when on the gas....The entire car shakes even when idling...Sometimes when starting it will stumble and the ses and traction control lights come on...Even before this started.....Havent pulled codes yet...Weird though, from one starting to the next( a span of 30 minutes) it started....
Oh, I can smell something like a match being blown out when I get out of the car after driving....Cat converter?? Never smelled this B4..Only after this problem started....

Sounds more like a possible bad coil, and or bad plugs and wires... Do or are the wires look to be original? If they have numbers on them they are most likely original... Look for the name Packard on the wires that will most likely be a dead giveaway... Look there and get the codes...
Also be aware that Autozone will not be able to scan the codes... The 1995 bonneville was OBd 1 compliant but used the OBD2 connector and OBD2 codes... So the OBD 2 code reade they use will not work... You will need a scan tool capeable of reading the 95 GM cars with an OBD2 cable... Good Luck and let us know what you find..
And yes the 3800'* have rev limiters... The internals in the series 2 engines lost weight and that makes it easier for the internal to spin, especially when not under load... You will actually rev limit at 3500-4000 rpms if the car is 15mph or less... Then you will have a fuel cutoff just after 6000Rpms...

update
OK, went to autozone and you are correct...They can't read it...I did disconnect the hot cable from battery and reconnect it....BTW, car alarms will freak out most dogs! 
haha....
I guess resetting the ecm corrected the issue but probably didn't fix anything....I'm sure it will come back...
Also I found a toggle switch under the dash in front of the fuse block...I turned it off and fired motor up and came home...Well, my theft alarm went off all the way home....People will stare at you when this is happening :? I flipped switch back and started motor and no alarm....And ideas?
