My damn car just started bogging down whenever I push the gas here in town and on highway and it can't hold idle. By the time I had driven 3 miles or so back to my place, the car barely had any power and was stumbling all over the place whenever I would touch the throttle, and at idle. It seems to be a wiring issue. I have no SES light though.

Ok, so I am in MD outside of D.C. for an internship and just got here two days ago all the way from TX (~1400 miles the route we took) and the car did perfect the whole way here getting 25 - 28 mpg w/4.10s and 130k miles on the stock 02 longblock. I have my tools but live in an apartment and don't have a jack and the way the 02 sensor is on the passenger side, I can't get it out without pulling the exhaust which is a no-no here. The car doesn't even have enough power to get it up onto the rhino ramps because it can't hold a certain rpm worth a damn!

What should I do? What could it be if not 02 sensors? How can I check?

Thanks in advance!

It could be a million things man. Car will run with bad o2's. Could be maf, map, injector problem, etc. You need to scan it, check for fault codes first. I wouldnt throw parts at it, because it could get expensive.

 

check your sensor fuse. it all ties in through that. if thats popped it will run like your describing. thats an easy start and you dont need a jack. you can continue on from there.

 

Sounds like it could be the coolant temp sensor. As said before, you could get a pretty good idea of what your problem is by swinging by an Autozone, and having them check for codes.

 

theres no codes at all....which is making me think that it might just be bad gas. im gonna try pulling the fuel filter and seein what the fuel looks like.

 

dang karl, that sucks. hopefully you can get it figured out. NOT a cool way to start off up there. hit me up and let me know how its goin.

 

I had this happen to my z karl, and it ended up being the wire into the back of the alternator

 

unplug the mass air sensor and start the car, let it idle for a minute and let it switch to speed density mode, then go drive the car, if it runs ok, its either the maf or the o2 sensors, the only real way to check which sensor is bad is to hook a tech 2 up to it and look at each one.

 

i think your car just hates you cuz you left texas and its surrounded by yankees.
