I have a newly bought truck, Grand Blazer 1997, 4x4, 8 Vortec cylinder engine. It worked very well, until a water stick fell and I had to go through a lagoon where the water reached half of the door. I managed to pass ... but the month began a fault as if it were electric, I thought that a spark plugs had fractured due to the temperature change. And indeed there was a game, I bought the new platinum, but the fault followed, changed the spark plug wires and follow the fault, well clean the MAF sensor, position of the crankshaft, the pressure of the admission chamber, the PCV valve, change the air filter. and gasoline. But continuous failure ... has no strength, it is as if starting at two speed. When I put Park, or stop or put it in drive with the brake placed the car trembles a lot. As if combustion were not complete or there were no cylinders without working. Could it be water in the gas tank, or damage to the box ?????
The last thing I did was to shine it and I threw a p0102 code error, which is the MAF sensor. Delete the code with the computer or scanner and improve a bit ... but today he presented the fault of the trembling, and has not turned on the bulb or check light the engine .. will they be the dirty injectors ???
