87 civi si Bogs on accelreation, eventually will stall

Hi,
I've replaced the map sensor,fuel filter,fuel pump,mfir, and oxygen sensor. The pgmfi light is on. It starts and idles rough,.When it warms a little, it bogs on acceleration, then eventually stalls. Any help would be appreciated. Thanks, Lou

I just got it fixed. I actually replaced the same things you did and couldnt figure it out. Turns out i had the timing retarded by a tooth. It made a huge difference. I got alot of help by posting here though too. Thanks guys. Ever since i put the new cam in it ran like poop. Took me 2 weeks of trouble shooting to fix it. As for the rough starting i couldnt fix that. Its just something i have to live with since i de-vacumed the car. It has no cold idle. If you have any questions let us know. I would def check the timing though. Good luck.

Bud,
Thanks for your input! This just started, it was running fine.I will check the timing but I don't think that is it. Thanks again, Lou

Have you checked the ECU code? When the PGMFI light is on that means the ECU is throwing a code. The number of LED flashes will tell you what the problem is.

Thanks for your input! I didn't have any lights on the computer! It ended up being the 20 amp fuse for the ecu didn't have a good contact. Runs fine again but the pgm-fi light still goes on under acceleration. I also have 1 and 2 light on. I replaced the map sensor a short time ago.? Runs good!!!? Thanks for the link.

Bud,
It was the 20 amp fuse for the ecu. Bad contact!!!!! Can you believe it?! Runs fine now. What ever happened to spark and gas???!!!!!!!!! Later, Lou
