Probably not worth the time or money All issues are computer related Vehicle height control system / Left rear Air bag problems ABS problems

I just had someone go through the whole car and they check the cylinders they check the all the compressions Jackson checked all the wires that they checked a lot of things could that have caused all these killings to come up I reset and clear the codes started the car and no error codes came up after I turned it off but one thing that the guy did tell me was that the car runs fantastic and then it starts to misfire and sputter and he said if I look under the car at night after driving it the exhaust manifold is red so is this the O2 sensor that's not working or do I have some other major problem

I know it needs rear air shocks and I just had new brake pads put on
