I have a 1994 5.0 f150 with an E40D and mass air. When I bought it, it would occasianally cut off in reverse but it has evolved to shutting off at first startup/idle unless I give it gas. Two days ago I noticed that when I floor it, it will start missing and not accelerate but I let off and it goes back to crusing. Is there any particular test I could do or do y'all know what it could possible be? Any help would be great. Thanks.

 

pull the codes. Also pull the trans pan to make sure the filter hasnt dropped.

 

Alright I'll pull the codes when my MAF sensor comes in. If I drop the tranny pan won't All the fluid come out?

 

you will loose some fluid. when was the last time the trans was serviced? Perhaps this would be a good time.

 

why are you replaceing the MAF sensor?

 

I'm not sure of the last time. I took the MAF sensor off to clean it and my friend broke a wire inside so he paid for a new one. It seems to be running a lot smoother now that I replaced that, it is NOT trying to die at idle or reverse. Ill drive it a little more tonight and see what happens. BUT it is still missing when I really get on it.. Any ideas?
