First, some back story. Purchased the car in October, drove it home 300 miles, ran perfect. Parked it for the next 6 months because of winter. Over the winter I swapped out the stock MAF and Mafia for a BA3000, did the EGR delete, installed a catch can, changed plugs and gapped them to .028. Contacted a reputable tuner from the site and loaded a base tune. Fast forward to spring, drained the old gas and dumped in some fresh 93oct, go to start the car and it sounds terrible and will barely stay running. Started to trouble shoot at this point.....installed a new BA3000, cleaned the IACV, double and triple checked vac lines for leaks and made sure they were in the correct places, sprayed starting fluid around the blower, etc. Nothing helped. Tuner sent me a few different tunes to try, still no luck. With the MAF connected the car will barely even run, unplug the MAF and it smoothes out a lot but still doesn't sound like it should, sounds like a cammed big block. Checked the plugs, completely back, pig rich. Wide band is all over the place, once it settles it pegs at 22.4, super lean, makes zero sense. With the MAF connected there is an overpowering smell of fuel coming from the exhaust, unplugged it gets better but still pig rich. Pulled the DTC's, P1000 P0243 P2195 P2197. Tuner said the first two codes are of no concern during a base tune, 2195 and 2197 are upstream O2 sensors lean. Cleared the codes and only P1000 and P0243 came back. I removed the catch can and installed new plugs out of curiosity, no improvement. Installed a fuel pressure gauge, reading 31-33psi during idle. Other mods to the car are Whipple 2.3, twin Ford GT pumps, single modded FPDM. The x pipe and catback are currently off of the car, running thru open headers, rear O2's are disconnected, I would assume they would be disabled in the base tune. Next step is to install new upstream O2's. I've attached video's of the start up and idle with and without the MAF connected and pics of the plugs. I'm running out of ideas and things to try, getting frustrated. Anyone had the same issue's or can possibly shed some light on what may going on?
