yeah and it lights up when it has circuit right?

 

when first reading this story i thought it was the fuel injector recall for the cobalt. I just recived my notice today.

 

[QUOTE=mattyfinch;805584]how exactly do you test an injector?
The best way to test an injector, while in the car , is with a fuel pressre gauge and a scan tool, Tech2, (or a device that will pulse the injectors for a precise amount of time). With the gauge connected, prime the system and watch for leak down on the gauge. If the reading drops, you may have a leaking injector, (no good at idle). Then you need to pulse each injector and watch for and equal drop in pressure, if one differs, you have a problem.

This does not pertain to te 2.0l, as far as I know.

 

in also running 60's

thanks dude

i also had code p0134 show on the tech 2 whats that?

 

How do you have so much power??290!!??

Sorry for off topic, it just I have pretty much the same mods and 40 less hp.

 

p0134= O2 sensor bank 1 insufficient activity. The O2 sensor in the manifold is not moving off it's bias voltage of 450mvs.

 

So it may be an O2 sensor causing his problems?

 

That sure is another possibility. The car will run like crap if the o2 sensor has gone bad.

 

It happened to me a few times on my other car.

 

but why the misfir codes? and thats actually a code for the heated o2 which is the back one, i checked o2 voltage and it was bouncing properly on the scanner. and 290 whp is muchly do to 24 * of timing, plus a **** load of meth, a great tune, and some secrets and it was 294 but i didnt feel that 4 was important.

 

The problem with that code is that it can be a cause or an effect. I would go for the lowest numerical code first or what is set as "current".

 

like my main issues is why am i getting the misfire codes, and maybe what i think im felling isnt a misfire? maybe its the issue with a/f ?

 

Do you still have the stock cat in the car by chance?

 

yeah i do... and ive ALWAYS thought it was fucked up... could it be doing this?

 

oooooo I thought that was without the meth, I understand now. Im planning on meth in the next months so hopefully ill be up there. Goodluck with getting the car running good again.

 

thanks, and if you get the snow kit run the 275 jet, its worth it!

 

I would definitely look into removing it and replacing it with something else. My car ran like total ass when the cat clogged. Pull the downpipe off as well, and turn it over. If the crap comes falling out or it looks like it's melted on the inside that is bad juju!

 

i just ordered a 3 inch dp with highflow yayayayayay

 

Them reflashing with your 60's will make it run stupidly rich. Don't do it unless you switch to the 42's.

 

Did you check those spark boot etc. yet?

 

not sure how too, the dealer is being really gay, they wont check anything until they do the reflash and see that it didnt fix ****. its ******* gay.

does anyone know if hpt supports the tsbs as well? like do they also get the update and add it into the software?

 

Oh, the car is at the dealership right now? Errrr..... That's scary! All my suggestions are based on checking this stuff yourself. I refuse to go to the dealership for anything more than parts now.

 

wat is the car doin exactly when it starts?, with out trying read up cuz when you start it and the idle is goin nuts, something is not connected right.
if you have a 2 or 3 piece intake, id check that to make sure the couplers are where they have to be.
this happnened to me when i had the jbp, set a code, couldnt remember which one and the car was just brutal.
checked the intake conenctions and prblem solved, i hope its nothing serious man.

 

i do and i will check, but that wouldnt cause THE MISSFIRES....the contant p0171 lean code is my huge issue!!!!

help

 

I dont know alot about this stuff...but it sounds exactly like what my dealer explained would happen if you have an injector crap out.

good luck with it.
