I have a 99 chevy blazer 4x4 automatic, I have been constantly having problems regarding some sensors? I am having problems with it burning fuel very rich, so rich it coats the ground in black exhaust and you can get a great wiff of the fumes( its wonderful, it you dont mind dieing), also problems with it turning over, sometimes I have had to pump the gas and even then it sputters and dies, after it does start my idle is only at 5 hundred rpms, give or take a few, sometimes it just jumps around, also the entire truck shakes from what appears to me to be the engine rocking back and forth( doesnt appear to be good at all to me) At first I was told it was my catalytic converter, had it replaced, not the problem, never was, told by another mechanic I needed a tune up and to replace fuel filter, wires, plugs, dist cap, rotor button, but once again the problem is still here, so I have talked with another mechanic and he tells me hes seen this before and its either the fuses or somewhere along the way the wires to my sensors were pinched when put it and all the wiring needs to be checked,( this I cannot do on my own), so once again I get advice from another mechanic and we run a scan on it, it get 4 errors,1- MAP (manifold absolute pressure) or MAF (mass airflow) condition, 2-IAT ( Intake Air Temperature) circuit, 3-Cylinder misfire and the fourth has to do with my transmission component slipping( which has been going on for a while now but does not seem to affect my truck unless I have driven for a about a half hour, when I come to a complete stop and the go it jerks into 2nd and sometimes 3rd, I was told this was a sensor in my transfer case that just needs to be cleaned? Anyways I went this morning and talked to yet another mechanic about the scan results and was told that a MAF sensor would stop all that was wrong with the exception of the transmission, so I buy this sensor and replace it, GUESS WHAT, NOOOOOO LUCCCK!!!! I have been fooling with this thing for the past year now it seems like and I have put way to much into this car to sell it and get anything near what I have put into. If anyone can help me I would greatly appreciate it. If you have any idea please feel free to let me know. [email protected]
