my fuel pressure is good 39-40 idle and drops to 31 when I hammer down brand new stock regulator on prob gonna put aeromotive unit back on tho. air filter new fender mount cold air intake. car def ran worse wit pcv hose off, I took vac line off top of egr, line has vacume car didnt run any different with it off. I had that egr off a year ago when I installed my 75mm t/b egr was clean and free moving but that was a year ago. I cleared the codes again but now need to put it thru a driving cycle and the scan tool I am using doesnt have a way to check maf. does that help any???

 

CODE 1132 A Heated Exhaust Oxygen (HO2S) sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

Possible Causes
See the possible causes for DTC P1130.

 

The Heated Oxygen Sensor (HO2S) is monitored for switching. The test fails when the HO2S does not switch due to circuit or fuel at or exceeding a calibrated limit

Possible Causes
Electrical:
# Short to VPWR in the harness or HO2S.
# Water in the harness connector.
# Open/shorted HO2S circuit.
# Corrosion or poor mating terminals and wiring.
# Damaged HO2S.
# Damaged PCM.
Fuel System:
# Excessive fuel pressure.
# Leaking/contaminated fuel injectors.
# Leaking fuel pressure regulator.
# Low fuel pressure or running out of fuel.
# Vapor recovery system.
Induction System:
# Air leaks after the MAF.
# Vacuum Leaks.
# PCV system.
# Improperly seated engine oil dipstick.
EGR System:
# Leaking gasket.
# Stuck EGR valve.
# Leaking diaphragm or EVR.
Base Engine:
# Oil overfill.
# Cam Timing.
# Cylinder compression.
# Exhaust leaks before or near the HO2S(s).

 

Possible Solution
A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S.

wtf is that???????????

 

The only thing I can add is to work the possible causes list from top to bottom, the information from my site (click here) is from the '03 shop manual so it may differ on your car in some ways...

 

now am getting P0300 code multiple random engine misfires

 

First off, I feel for you. I have spent a lot of time running after codes.

But to my question... were you being literal here, or just trying to express your frustration? If literal, you have more problems than you thought. In a normal drivetrain, your speed is directly related to your engine RPMs, ie in any given gear, your engine is going X RPMs then your wheels will be going (X times a constant) RPMs, the constant being derived from your tranny and rearend gears.

 

damn sounds like my car. idk wtf is wrong with mine either i said fck it idk if it runs any diff now than it used to. i have the same exact problems and codes. all i came up with for mine is probly a bad pcm, probly the same for you.

 

ok well i just took a video of how mine is doing and im about to upload it

 

well lets see this vid to see if mine is doing same thing. also I gonna clean my maf sensor
