Strong gas smell when starting

Z_ealot

Just climbing up on 158,000 miles, the only roughness i encounter is when the stft pegs itself at +25% and then the engine stumbles and almost stalls and then that’s when the fuel trim numbers flip and the idle smooths out again, curiously the engine seems to act like it’s choking after this when i go to accelerate and does not really pick up power till after 5,000rpm.

How's it drive with both mafs disconnected?

Acts like it wants to die with both disconnected at idle, rpm’s fluctuate between 1500 and 600rpm, both maf’s are new

That's odd, I haven't tested this on the Z but typically a car will default to safe mode that almost always runs smooth with no MAF reading (usually a good indicator if the MAF is bad if it's smooths out with it disconnected). I'll have to test it on mine.

Have you checked the basics like vacuum leak?

Triple checked and couldnt find any leaks even trying to hunt one down with soapy water. The only suspicious thing i happened to spot was what looked to be a tear in the outer part of of the intake manifold gasket.
