Abs, TCS and 2 codes

Asked by Feb 19, 2015 at 10:25 AM about the 2003 Pontiac Grand Prix GTP

Question type: Maintenance & Repair

I have a 2003 grand prix gtp. I am having a problem with the
abs, TCS and the check engine light flashing. The engine
light is for no.4 cylinder misfire and no.4 injector.  Now all
this happens at once and it makes the engine run ruff. Any
ideas?

Well as far as the abs and traction control thats the front hubs ( bearings) as far as the misfire that could be a bad plug or wire or bad coil. The other side of that could be a faulty injector .

I put a new wheel beraring on it. once and awhile when I start the engine it runs real ruff, scanner says injector 4 malfunction and cylinder 4 misfire. service engine soon light starts flashing and the abs and TCS lights come on. After a few minutes the engine clears up and the abs light goes of till it hit the brakes.

Did you do both wheel bearings? Wheel sensors can also be a problem and worn out axle shafts also seem to cause problems with ABS and TCS.

Yes I agree with munron always do both hubs. It's a gm flaw. All gm cars with the sensor in the bearing are a pain. The misfire .... there is only two things to look at ,,,spark and fuel.

It's just weird how they all happen at the same time. I've had both front hubs tested and they check out good.
