I'm having an issue with my M50 swap and was wondering if anyone could help. On start-up my wideband gauge reads aroung 14.6 (good), then the idle changes a little and the gauge drops to rich (11.2) then shoots back to 14.6, stops there, and then slowly climbs to lean stopping at 16.8ish. The ratio stays in the high 16's low 17's through the rpm range. At idle the gauge is jumping around a bit.
If I disconnect my maf the car sits at 11.2 and doesn't budge, if I disconnect the O2 the car sits at 17.0 and doesn't budge. Neither causes a change in idle speed or stalls the car.
I just replaced my MAF, plugs, valve cover gasket, ICV, cam position sensor, fuel filter, and fuel pressure regulator. I'm getting good pressure at the pump, filter, and inlet/outlet of rail. I also checked extensively for vacuum leaks with both compressed air through the intake and with carb cleaner. Everything seems tight.
More about the car: M50 with S50 cams, tune unknown (previous owner), I haven't driven the car in 5 months because I've been working on it, but it starts right up without a problem. Is there a chance bad gas could do this? It seems like some sensor to me since the car seems to get it right at startup, then something goes haywire.
Thanks in advance for any input/help.
