I replaced the O2 sensor and startup was not great, but not absurdly bad--although this coincides with the weather changing here, so I'm not sure if that changed anything. I tested the IAT and it seems ok, according to the generic youtube voltage test. There is an MAP (thing attached to firewall). Or is that MAF? I get confused.
Yesterday, my fuel pump died! Maybe that's been part of my troubles. I replaced the strainer and the little length of fuel hose (both totally disintegrating) and was getting 30 psi running pressure (40 to start), with quick pressure loss after shut down. Last couple days the pump would run intermittently with key-on, and today just before death, wild variations in pressure while running. I guess I need to check the tank for age issues too. Is there any difference between the various fuel pumps rock auto offers? I'm obviously leaning towards the cheapest.
Thanks,
Darren
