I’ve moved coils around, no change. Replaced plugs. I’ll inspect the wiring again.

Well, replaced the turbo gaskets and that fixed the exhaust leak. Engine still runs terribly though. It misfires almost all the time now. Before it was only really bad when engine was cold. Severe hesitation/lack of power at low RPMs, smooths out above 3k. Backfires a lot and engine vibrates. Fuel e...

Found a significant leak at the turbo going to the manifold. Didn’t see the leak last time I smoke tested exhaust. Ordered new hardware kit from Corksport.

With LTFTs reset, using stock CX-7 partition breakpoints, the STFTs are around 10-12% at idle and they increase from there, maxing out up to 25% even under light acceleration. Well, that is one reason why we use different fuel trims partitions, because the stock calibration assumes that a correctio...

It's hard to tell because of how the MAF partitions seem to be in the tune you used when you took those logs. However by judging how the AFRs bounce from stoich to rich with steady LTFTs and then how at idle the AFRs are around stoichiometric but the STFSs suggest that the ECU still wants to pull m...

Still chasing AFR issue. Engine is running "lean." Adding lots of fuel with fuel trims. Fuel in oil. Checked for leaks, could not find any with smoke test. Getting P0300 random misfire, sometimes a DTC for specific cylinders. Compression is good, 200, 190, 185, 195. Cylinders are dry. Trie...

hey Zaclaw, Long story short, I Have all the same upgrades as you plus the 72mm throttle body from Corksport. im "barrowing” your tune from the other thread you posted it in. My question is, what octane tune are you using? im here in Cali so I don't have access to 93, but will use octane boost...

It seems that unplugging the purge valve only made the rich AFRs slightly better. AFRs are still oscillating, mostly on the rich side. Hitting down to 9.4 when minimum allowed is 10.29. Oil does smell of gasoline but the level is on point. Still no CEL. All other readings appear normal. What should ...

The problem appears to be caused by a sticky purge valve. I unplugged it. Then I disconnected the canister-side hose to make sure there was no vacuum from the nipple with the engine running to make sure the valve wasn’t leaking internally and that it wasn’t stuck open. No vacuum felt at idle. Test d...

Ok I’ll check the level after it has sat for a bit. As far as I know the HPFP seals are original with the car, 216k miles, so seems likely. Wouldn’t a stuck injector cause a CEL or misfire? The idle AFR seems stable. For an exhaust leak to cause excessive richness, the leak would have to be before t...
