Is there a code/check engine light?   jon denouden (Jpdenouden) New Member Username: Jpdenouden Post Number: 2 Registered: 06-2003 Posted on Friday, June 13, 2003 - 12:14 pm:    the spark plugs had alot of carbon on them. there is some smoke and smelly exhaust gas coming from the exhaust. the lake of power feels like I'm driveing with the brakes on, and no the hand brake is not on and the brakes are not draging. thank you for helping   jon denouden (Jpdenouden) New Member Username: Jpdenouden Post Number: 3 Registered: 06-2003 Posted on Friday, June 13, 2003 - 01:18 pm:    I checked the code box and found (44). so i pulled the os/sensor on the left side. It was full of carbon, so i cleaned it and put it back. I also pulled the stepper motor and found it full of carbon. I cleaned the carbon off and replaced it. Then reset the code box and still got the (44). can you clean on o2/sensor or do i just have to buy a new one. thank you Jon   Tony Zuniga (Tony23007) Member Username: Tony23007 Post Number: 93 Registered: 05-2003 Posted on Friday, June 13, 2003 - 10:05 pm:    If its a 95 check the timing, that will cause it to run rich if its advanced.   Ron Brown (Ron) Senior Member Username: Ron Post Number: 416 Registered: 04-2001 Posted on Friday, June 13, 2003 - 11:21 pm:    Buy new O2s both of them preferably. its time.
