This weekend, I checked the occasional engine codes on my 89. 42 and 32, 32 = egr 42 = ignition timing. Suspected one of them to be related to the shitty clogged up cat, so I went ahead and pulled that off.... Then since the misses was gone, I had to drive to the store, and do some other errands like that around town.. Boy what a joy, open pipes around town. the code 42 is related to the EST circuit not advancing timing like it should when I accelerate, essentially I've been driving maybe the past 2 months on base timing, plus the.... 5? Degrees mechanical advance from the ignition module Something lousy like a total timing of 15-20° at WOT LOL LOL Even for a HO350 with higher compression and 93 octane, she still runs like a bone stock tbi 350! Lol Explains why it's been a turd and getting shitty mpg. Regardless..... First order of things is to bypass that cat with a straight 3" pipe to the muffler, and from there, I'll work on getting to the bottom of what's causing the timing error. I should've just bought a new dist instead of just doing cap, rotor, wires, and plug. Good times.
