Hey Xanth I fixed it.It turned out to be the dis module all along.

Thanx for the addy,I will keep everyone informed as to the progress of the car.Who knows somebody else may run across the same trouble some day.I thank everyone for their help so far and in the future,lord knows when you own a Fiero you need all the help you can get.

Well I kidna figured as much.If the ecm took a dump it would run bad all the time but it was worth asking.That would be cool if you could hook me up so I can get on pff.I could really use some help with this car cause it's driving me crazy trying to figure it out.I noticed that there are alot of 4 banger guys there that may be able to help me out.I saw the bulletin about the stolen fiero convertible,I was not aware that any were ever built.It looks really good,I hope they dont find it smashed and decimated.It would be a shame to destroy something like that.

Hey Xanth,I just read your comment on PFF where your Fiero stumbled and ran poorly when the ecm took a dump.Is it anything like the trouble I'm having?I am trying to get signed up there but I remember my username for my att dsl and it wont let me sign up on my yahoo email account.

Ok I'm stumped.New coil packs didnt do it either.I am out of ideas.

One of the first things I tested was compression.Highest cylinder was 128, lowest was 123.I am starting to wonder about the coil packs.They look old and are cracked in spots.Could it be them causing this kind of trouble?The car still acts like way too much fuel not being burned in the cylinders and it smells more rich than normal.Maybe I'll throw some more money at it and buy some soon.I'ts only money right?If nothing else it will have a bunch of new parts on it when I'm done,lol.

I am not sure what model you have but on my 87 base notchback the ALDC is behind the cigarette lighter panel.Just remove the 2 torx head screws that hold it on and the connector is right there.

Ok new update.Installed a new o2,tps and fuel pressure regulator.Absoloutly no difference.I guess throwing new parts at it aint the answer either.So any suggestions are welcome.

Nothing new to report,just too damn busy.I havent had time to go out and fire it up.Maybe someday next week I can get something done.

Ok it's been a couple days but I have been bustin hump at work and have 0 time to spend on the car.I would like to say I have an update but I dont.I am picking up the O2 and TPS tommorow and slappin them on and gonna give it a go.I will update 2moro.

I think I'll get the O2 tommorow and try it first.I also found a few ecm's on ebay so if the O2 dont do it then I'll grab one up.

Any idea on what would cost.I have heard they can get high dollar and I'd hate to drop a ton of $$$ to find out it wont help.I just read on pff that a gent was having similar trouble swapped out his o2 sensor and cured it.Is there a test for the o2?

Yup,1 bottle in the tank with 5 gallons of fuel,no luck.I do appreciate your help with this mess and I'm sure it will work out it's probably one of those silly little things that takes 2 seconds to fix and 2 months to diagnose.It is what it is.

No cat,no muff,just a fart can.Not my idea that is the way I bought it.

The redline is 5000.I did notice while i was running it earlier that the fuel spray at idle was a fine mist cone pattern.As I accelerated it became a tighter higher volume almost stream and it was backfiring through the exhaust.Is this spray pattern common?
