desperation bump.

bump

[call me jack]

Tested my o2 sensor. Got no voltage response at all. so i'm either really lean or the sensor isn't working. i even pinched off my return fuel line to try to force it to richen up.

[call me jack]

you think if i pinched off my return fuel line i could effectively test my fuel pressure regulator?

(I don't have a fuel pressure tester)

is there any way to test for a reference sensor?

you can test the reference sensor with an ohmmeter. the resistance should be 500-600ohms. i don't think that's gonna be your problem though.

Make sure you plugged your AFM in all the way.

i just double checked. yeah, it's all the way in. i don't even know where to start at this point!

did the problem just start out of nowhere?

yes. but i did replace my alternator the day before if it's of any consolation

plugged cat or exhaust system ? easy enough to drop header pipes to diagnose

could that really hinder performance that radically? i get 27mpg

is it in limp mode?
i say check your ecu...plugs, timing? crank position sensor?

today the rpm level dropped to 2k before it started doing this, so it doesn't sound like a limp mode. does this car even have a limp mode?

i did a load test on the fuel pump. 3.34 amps. thats well with in spec.

^so if i piggyback them i can get to 11k?

if you have an aftermarket chip that increases the rev limit to 7k, make sure you didn't put it in backwards. it can have the reverse effect and drop the redline down to 3k.

(i am kidding... please don't open up your ECU)
