My new summer job ($$tuition) is delivering pizza's in a Beach resort. First day went fine, about 200 miles, 10 hours, of hardcore city driving, with the ac on (steamy pizza's fog up windows). Lots of acceleration and stopping.
Day 2, just before I got to work, I stopped to get gas, od just hit the 180K mark. I was checking the tire presure when it stalled. I thought to myself, fuel pumps or something. Cranked it no go. Saw the rear view mirror, white cloud. Looked at the tail pipe, wet with fuel. Popped the hood, fuel pressure regulator gone, hole in diaphram. Fuel in vaccum hose.
So I borrow my sisters 740 and exchanged the fuel pressure regulators (radio's better in my car). Started and ran fine. Got to work. After my first delivery, I left the car running and locked it with a spare key, don't want to wear down the starter.
I return to find it having a hissing fit. All orange lights on the dash are lit up! Lights fuse, service and check engine! I checked the codes, and sure enough, O2 sensors gone. Running very rich. And fault in injector wiring. Also blew a tail light. Drove it the rest of the night. Lots of fuel.
The question: I had called a local Auto Zone and asked them if they sell the same FPR for both the cars (740 & 240), and they said yes. Now I that I've looked at thepartsbin, they are different!
Would that have damaged my o2 or the excess fuel when the FPR failed? Remember there was fuel in the tail pipe.
Came home checked volts on o2, don't change which high idle. Only get about 3 ohms on hot o2.
I have decided to beat down on a Honda Accord instead, no one really uses it and it gets great gas mileage. It passed the test (3 days) so far!
