Thanks for the replay, and I put the car on my scan tool and its coming up as " Ignition coil B malfunction" and I know that all the coils are new. Im not too car savy so im pretty stumped on this one, but the car does idle roughly and the car nevers stalls in park, but when the rpm goes way down the battery goes from 14.2 to 13.2 and you can tell because all the lights in the car began to dim out. Im still checking out the car right nowAs we're both waiting for replies to our posts, I'll say, yes there is a reason - it's a 17 year old car.
Can you give more info than that? Does it just not stay running after you start it? Does it at least warm up before stalling? Any rough idling/misses? Have you checked fuel pressure (schrader valve on top of fuel rail), cleaned MAF (gently spray brake cleaner onto filament, then blow canned air onto it), changed O2 sensors (only gotta worry about the 2 upstream of cats)? Are you running original coils? (I'd be shocked). ****, run 10 oz or so of Seafoam through a full tank of gas. I ran some through my intake a few days ago and when I disconnected the brake booster line from the junction (near driver's side strut bolts) the car began running VERY rough, but didn't stall.
