running weird??

mustangrebuilder · April 22nd, 2008, 02:52 PM

ok so last night i stop for gas, car is running fine, go to the store and back to my apartment and everything is fine.

i get up this morning to go to school and the car almost stalls but i dont think anything of it was kinda cold out side, then after school it does the same thing, but not as bad, and then it seems like i dont have any pull until like 3000 rpms, at first i thought it was jsut me but then when i finally got out of the parking lot i got on it hard and it still didnt seem to pull until the same rpm range, it idles fine, but then i got to my apartment so i shut the car off, wait a few seconds and then start it up again, starts fine, then sitting here it has a weird idle, i heard somehting and it sounds liek the exhaust.

i was thinking it has some thing to do with the gas i put in it, maybe bad gas.

i have a 93 octane tune, and i put 93 in it.

and i was also thinking it could be a plugged cat, cause i know that causes a lose of power, this happen to anyone else?????

Damn your cats are on crack?

I blew 1 of mine out, the ones with the Dynatech LT's and luckly it was on the dyno and we seen the car go way lean and the drivers side exhaust gasket blew out, we did some investigating and found the drivers side cat sitting against the rear O2 sensor about 12" from the housing

qwik48r · April 22nd, 2008, 03:07 PM

probably was... where they are positioned on these motors, they see ALOT of pressure... i wouldnt be surprised to see these thing become a prob down the road... your smart to get rid of em... remember to take em to a junkyard for some spare cash

mustangrebuilder · April 22nd, 2008, 08:14 PM

^ yeah just started happening this morning so it wasnt forever that it was getting that bad of gas mileage thank god!!!!

it was just cause of the intake tube being off, running lean and dumping more fuel to compenstate for it
