Driving down the road with my 91 EFI and she gets a case of the coughs. <img src="/forums/images/graemlins/barf.gif" alt="" /> the check engine light flashes every time she lets one rip. like almost an electrical problem like the spark just kills for a second. i thought maybe some water in my fuel so i got some good gas and put some alchohol in it and it still does it. no matter what speed what angle. it will do it for a bit and then run good for a while after that. no telling when it will do it. also it seems like it just does it when in gear. i can rev it up and it doesnt seem to do it with the clutch pushed in. this is my daily driver and i need some serious help. PLEASE and THANKYOU
