High water and Blazers dont mix

[mhwpd108]

We had a really bad storm here tonight, and i ran into some really high water, and then my Blazer cut off, and wouldnt start for about a hour of sitting there, and finally after trying to start it a few times it finally turned over and cranked, and then when i was riding down the road it was jumping a little, and either smoke or steam was coming out the mufflar. And then a little ways down the road it all ran fine but the check engine light is still on. Anybody know of anything??

new plugs and wires, change ur oil and ur air filter then see what happens

cap, rotor, plugs, wires, oil, air (if needed) and O2 the light is on cause of the o2 got wet and is shorting out if it is an older truck read the code

if its a new truck the code most likely a mis fire code due to the water on the wires casueing them to arch out and making a misfire. find out what it is and if nother major clear it and see if it come back on.

I went out and cranked it this morning, and the service engine soon light isnt on anymore, and when cranking it, it doesnt sound like it did before. When i first crank it, the oil pressure gauge is high for a little while then it goes back down.

I was told by a mechanic to take the spark plugs out and turn the engine over a few times to blow the water out of the pistons, and change the oil, and that should fix the water problem.

Well i had my Blazer scanned, and it was the Throttle Position Sensor that went out!
