I recently installed headers, egr delete plate, smog pump delete, new 3.42 10 bolt rear end, and a hypertech tune. Ive been driving it now with no problems and loving it for about 200 miles now. However, today as i was driving over to my friend's house in the rain my car started losing power and stalled. I pulled over and started it back up and it was fine for about a mile and then it stalled again. It will idle for about 2 min just fine and then the rpms will start to drop and it will stall. It wil stall sooner in gear. I have a 95 auto 4 car. It doesnt misfire it just stalls. I also put the stock tune back on with the hypertech programmer and it still does the same thing. I have no idea what is going on. If you guys have any ideas it would be great the car is my daily and i really need it running right.

Got about $200-$300? If so get a new opti

Would it be the opti if there is no misfire? I have never had an optispark go so i dont know what its like when one goes.

dirtynorth

any ideas???

sounds like a opti or fuel problem to me

dirtynorth

well thats what i was thinking but im trying to figure out if it is an opti or something stupid with fuel would the fuel filter do this

Are you getting a SES?

dirtynorth

nope no light would the heavy rain today cause any problems?

an easy fuel filter swap and checking the fuel pressure can rules out a fuel issue

Agreed.
I've seen a few threads with issues happening after heavy rain...either with moisture getting inside the opti or bad wires arcing.

I had almost same thing happened to me, my car would barely move and RPM's wouldnt go pass 2500. Turned out it was a clogged cat...
