Rough cold idle(+ some other problems)

BladeX10 · 11-02-2009, 03:55 AM

It seems like for the first 2-3 mins of a cold start. My fox runs like complete ass.. Itll die if i dont touch the throttle a bit..The rpms go up and down to around 500 to 800. As much as i like having fun standing behind my car thinking i got a big ass cam.. It needs to be fixed. Once its warm its fine.. Drives fine aswell. What can the problem(s) be?

Also.. My car seems to have a really weak crank.. its just really slow and worries me alittle.. Happens more when its warm. Is it the starter right? But the other day my battery was dead at the gas station and after a jump.. it started fine.. I still believe its the start right?

Also.. Is it normal to have fumes take over the inside of the car with an offroad mid pipe? i got a big headache 5 mins into my drive due to the fumes.

first problem, sounds like mine, IDK what it is, pull codes and let us know. My dad says it might be a faulty TPS since its been getting worse and worse

second, might be the starter, or the battery isnt being charged right, take it to autozone and tested

3rd, check the connections after driving around, sometimes they'll loosen abit due to the heat cycling

Yeah ill find some info out about that idling problem.

Also.. Can having regular gt exhaust with the turndowns in the back contribute to the fumes in the car? as to having the exhaust tips going straight out to the back?

IDK, my GTs have their exhaust straight back
