HI, i just bought this 96 Jimmy, it has 240,000 miles. it is giving me a code (multiple cylinder missfire) and it has black smoke, backfires, hard to start. Has put the transmission in "limp home mode" second gear only. I also got some information from the code reader But i dont know what it means... Can someone help me please! ? it reads for the IGNITION ADVANCE: -24 Does this mean that it has the wrong timing? is there any thing i can look for to tell it has jumped time? Thanks SO much in advance Cory-
I realize it has high miles, and that is why i am not ruling out any possibility. It is in great shape regardless. and it will be fixed. The engine sounds good. no knocks or ticks. I have a 97 s10 with over 300,000 miles. on it still runs like new !! I forgot to mention, i have pulled the upper intake plenum off and i replaced the fuel regulator, and the spider looked good as well. Thanks Again. I will look at the distributor shaft that is a good idea..Thanks
RULED OUT - (i replaced already)
not the wires cap or rotor
not the map sensor
not the mass air flow
I cleaned the egr
