Having all kinds of issues now. At quarter throttle the engine will cut out like a huge misfire and sometimes back fire really loud. Not the usual popping on decel but a bang like a gun shot. Hesitation is horrible

What has changed?

Do you know your AFR's when the popping/hesitation occurs? I'm going to assume it's pretty rich.

I have finally gotten to get her back on the road after sending her off to have the wiring fixed by a friend during the pandemic. I am not having the shutter or cut out issue like before, found it was the ECU causing it to cut out. Pulls nice and hard to 4k and has much more but I am going to play nice for a while. Still feel like I will fail emissions but I will be trying again tomorrow.

Hesitation and popping are gone. Just got the AFR and boost gauges installed.

AFRs are:
Idle-14.7
Cruising-14-15
On medium load 2000-4000 RPMs is drops to 13 stays steady.
Heavier pull it will go to 12 sometimes.
Then letting off the throttle and exhaust pops a bit it pegs past 20+ for a split second and goes back to 14.7.

Those AFR's are a little high. What boost are you running? I know the feedback I heard was to try and stay in the 11's.

I do get the CEL to flicker if I run it fairly hard to about 4k and get codes 24 and 45. Seems like pressure codes possibly boost too high? If I cruise slow through the gears light boost the flicker goes away. No fuel cut to 4k. I have not pushed it past that though.

Usually you address the lower code first, which would be the IAC valve....and that really doesn't make sense given the circumstances. Honestly, it still sounds like an electrical gremlin issue.

Emissions has been passed! Looks like cleaning up the wires to the ecu fixed the super rich issue. Still get a CEL randomly but getting somewhere. Spent Wednesday cleaning her for 7 hours. Every inch sitting for 6 years was covered in all kinds of stuff. Still not finished but it's getting better.
