PostSubject: My car just started fing up REAL bad.   Thu Jun 18, 2009 10:46 pm

I was just driving home from Burritos....

I was about three minutes away from my house, driving through pretty steady rain... Few big puddles in the road that I blasted through and sent huge waves everywhere....

All of a sudden my car started stumbling and jerking and making a horrible noise from the exhaust. It had no power and sounded dead.

I don't have a wet opti; at least that I can be sure of.... What else could cause this? Maybe I got water into a plug wire? Maybe my car is fucked? I can't be having a car I can't use in the rain....

Check you cap and rotor for moisture inside.

Sucked in some water through the intake maybe?

My old Cavalier did the same thing. Turned out the pcm was mounted in the lower fender and got splashed so badly that it shorted out. The dealer replaced it under warantee and then put a leather cover over it to keep it from happening again. The car ended up dying for good a few months later due to a major electrical fualt some where between the pcm and trans.

It's possible that the pcm got a good bit of water inside it or at least in the connector and caused a short. It's not super likely but it is something to check into. Espeacially considering the iffy pcm location on a b-body.

B. Mac, my distributor is buried so far back in the engine bay......

Brad, My PCM is actually an ECM and it's located inside the car.

Crovo, the car is still FRICKED a day later.

I dunno what 2 do guys....

There is no residual moisture under my hood.

EXCEPT 1 spot. The charcoal canister is all wet at the bottom. Is the canister open on the bottom? This is the only place I see a wet area.

Also, I might have found a broken spark plug.... I gotta jack the car up to see. Will report back.

I checked the cap and rotor..... There was no visible moisture.

Also no moisture around the coil. Again, this stuff is so far back in the engine bay I don't see how it could get wet anyway.


Well..... I didn't find a broken plug. BUT, one of my spark plugs was HAND loose! Just jiggling around in there. The wires seem maybe a little loose too... Maybe not dunno.

A loose plug could definately cause this issue right? Especially after getting wet?

Unplug your underhood light (if you have one).

Shut off all outside lights.

Start it up tonight in the dark.

Find the lightening.

Replace that part.

No luck Crovo. No light anywhere.


It is not happening at idle when I turn my car on. It doesn't even happen when I rev the engine in Neutral.

It seems now that when I hit the gas while driving the car just absolutely dies and sounds absolutely terrible. Then it starts lurching. The more throttle the worse it drives.

I'm not too happy bout this.

bill i forgot that is a tbi. if it was mine. i would line up the crank pulley up to tdc on the pointer. then take off the distributor cap and see where the rotor is pointing. damn its been so long since ive done this. hope im right. that will tell you if you have timing has jumped. good luck.

you need to scan it and look at the TPS see if thats working normal and look at the O2 sensor readings see if their running lean

I scanned it Bobby. All sensors were acting normal. 02 was switching back and forth between lean and rich.

It seems to be gradually getting better? I was able to get on it yesterday and actually hit 100mph. But now it bucks under steady acceleration.

If I floor it there will be a hesitation; then it goes. At steady acceleration the RPM's will sometimes jump 1500 or so in either direction.

I know a lot of people will disagree with me on this one, but I think it could be the fuel pressure regulator. I had this same problem and threw all sorts of parts at way back when I had an 85 Impala with a 4.3 tbi V-6 and then had the same problem with my 89 9C1.

The loose plug issue has come up but......
Only thing I've heard is Fisha blasts thru a few big puddles & the car starts stumbling and jerking. Sounds now like its gone from awful to better without any help.
I wish it would get sunny out to bake that car & entirely rule out the moisture issue.
Wish I could point a finger at something. Only time I had anything like that was when my opti was on its way out & the rain /moisture made it start hard. Once started it would stumble & sometimes even needed a restart to fire right.
