hey guys i was wondering if you could possibly help me with this problem ive been having for a while now. my cars been missing alot recently sometimes its really bad other times its just a little hic up. yesterday i put new plugs and wires on and the problem is still there. Another thing is, i know for a fact i have a bad o2 sensor and my idle is around 1800 rpm at start up then i have to use the clutch to bring the rpms down to 1000 where it will stay there until i shut the car off then have to do it again. But right now i was wondering if the o2 sensor would cause the car to be missing? any imput is greatly appreciated thank you.

 

CEL lamp on or flashing?? Any trouble codes??

 

yes the cel is on and i tried to have advance auto pull the codes but they said their scanner cant read obd 1.5. but the good news is i did go ahead and replace the 02 sensors and they were a burgundy red color and they weren't the same. so now it runs great but now my only problem is slow throttle response.

 

Lag in throttle response could be anything from a fuel pump to a fuel pressure regulator to a bad coil or wire. Really it could be anything. Throttle positioning sensor... etc.

 

If you have been driving the car like this for awhile there is a good chance you Cat is starting to plug up.

 

well the plug wires are new so the only thing that could be is maybe a defective one? and i dont have a cat on the car.
