BC 00GT

Ok so here it goes!

My 2000 GT is Running like CRAP its stumbling and sputtering on light take off and has a very Rough idle. But it seemes to be ok on WOT, i reset my comp by disconecting the battery and it seemed ok for a few mins then it got worse. I have to go and get the Code numbers again as i dont have them right now!

We just replaced all plugs and Plug boots! and switched the COPs from side to side!

The problem remains with the Passenger side! we thought it might be a Fuel injector so i started to pull the fuel injector wires well it was running and NONE of the 4 Passenger side made a diffrence in the idle when disconected!!

So basicly There is somthing up with the whole Passenger side?????

any ideas would be a great help as it seems to be running worse and i am out of ideas

thanks for your Time!

have you checked your 02 sensors. i had the same problem for a while and it turned up to be my 02s. swapped em for new and havent had a problem since.

Might be your IAC, and doe's this happen when you have the A/C & Heater off?

BC 00GT

Yeah there is no Diffrence when the heater or A/C is on or off atleast not that i can tell!

When we pulled the codes the first time i told the shop just to Ignore the O2 codes as i have no cats and it always shows O2 codes but i am going to get them read again tomorow and i will get the Code number it is showing!

so from what i am reading. all four of your passenger side fuel injectors were plugged in and it ran like crap. so you unplugged them all and it made no difference... so something in the computer is telling your passenger side fuel injectors not to work? passenger side O2 sensors perhaps? highly unlikely, but maybe clogged injectors
