Fuel Filter

jahernandez · Feb 10, 2013

I went to change my fuel filter today. I disconnected the switch in the back to stop the fuel pressure
And my car stayed on for about 6-7 minutes before dieing. Isn't your car supposed to shut off after about
10 seconds?

jahernandez · Feb 11, 2013

Bump.
I decided to go ahead and purchase new fuel injectors for my car today and I'm pretty sure you also need to disconnect the inertia switch in the trunk to do this job. I timed the car this time and it idled for about 23 minutes. Is this normal?

Instead of disconnecting the switch try pulling the fuel pump fuse.

Why do you need new injectors?

jahernandez · Feb 12, 2013

I switched them because I am getting misfires and some backfire.
So far I've switched all the plugs and pulled the injectors last night to change them but none of them
had any gunk inside of them so I took the injectors back and put mine back in.

The car on take offs is running as if I were going up hill with it in 5th gear so it turtles along unless
I gun it and launch at over 2k rpm then it drives normal for about 20 secs then bogs back down. I can mash the throttle into the ground and the
car will accelerate SO SLOW. Sometimes after launching and getting it to run good the car's RPMs
will sit and idle at 1900-1500 after it is out of gear as if i were still on the gas and it will run fine the entire time but once the rpms
reset it will run crappy. Also while sitting at idle the rpms go up and down from 1000-400.
Car has a strong oder of gas as well like it is running really rich. I'm getting bad MPG.

Sounds like clogged cats or egr issue to me.

jahernandez · Feb 13, 2013

I don't have cats on it. I have longtubes, o/r x pipe, and flowmaster catback
It's as if the car isn't getting fuel. That's the best way I can describe it

Is it setting any codes? If it is get them read and check back.

jahernandez · Feb 13, 2013

It does have codes to be checked but it's at a shop getting some work done.
I'll check back as seen as I get the car.

jahernandez · Feb 14, 2013

Alright I got the car back about 30 mins ago and its not throwing codes (battery was disconnected) I'll drive it till they turn on and scan it with my SCT Tuner that should be arriving in the mail tmw then I'll let you guys know what codes its throwing.

COramprat · Feb 15, 2013

Check.

jahernandez · Feb 15, 2013

Alright guys I drove the car fine all morning but I can still tell there is something wrong with it.
The codes it is throwing are P1000, P1132, P1151
Would these just be both of my upstream O2 sensors on both sides?
P1152 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2
P1132
Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 1

Kilgore Trout · Feb 15, 2013

Did you google those codes?

jahernandez · Feb 15, 2013

Yeah. I'm reading about them right now. I guessing It is driver and passenger upstream sensors?

jahernandez · Feb 15, 2013

I just got back from driving that car and decided to hook the tuner back up to it and see if it's throwing more codes.
It is now throwing P1130 as well as the others P1000, P1132, P1152

Jhussey1280 · Feb 15, 2013

car's running rich according to the codes. what ever you changed seems to be dumping more fuel into the engine and not burning it all.

jahernandez · Feb 16, 2013

Hmmm yeah the car has a strong odor of gas and is getting horrible MPG about 8 or less.
Does anyone know what could be causing this?
The mods on the car are Long tube headers, O/R X pipe, Flowmaster catback, SR performance CAI, SCT Tuned for
performance on 91 octance (with my parts added into the custom tune, after I tuned the car it's running great but
i'm still getting awful MPG and I have those 4 codes stated above) Those parts are all I know of at the moment since I was not the
original owner of the car.

Might be a vacuum leak. Make sure all you hoses are good in the throttle body area. PCV clean and connected too. Clean the MAF sensor.

jahernandez · Feb 16, 2013

Thanks for the info so far guys.
Do you know of a easy way to check for vac leaks?
I'll go check my hoses here in a little and clean up the MAF.
I can use throttle body cleaner on the MAF right?

Use MAF cleaner only. TB cleaner will ruin the sensor.

jahernandez · Feb 16, 2013

Okay thanks. I'll grab some from Autozone once I'm done checking for leaks.
I keep you guys updated.
