    i just watch my local news and found out that a area gas station mistakenly surplied customers with diesel gas while purchasering regular unleaded unforturely i bought some gas from one of the station less than two minutes after pulling off the truck(97 tahoe 5.7) cut off and refused to restart i thought maybe the fuel pump went out, so i replace it. not knowing the gas might be bad i put it back in the truck it started but would not idell correctly ran good while driveing but need gas at stops to stay on i thought maybe o2 sensors so i replaceed the down stream one. started it same problem by now the bad gas is gone. so the next day i go to start the truck it wont start i buy the two more o2 sensors up stream but the truck still wont start any suggestion ?

For a larger engine, they could still be missing but you won't notice it once it is turning above the idle speed.
For both of you, I would suggest you check under the hood in the darkest area you can find and with the under-hood light disconnected if you have one, for sparks along the sparkplug and distributor leads.
I had to replace all of them after only four years on my lousy GM vehicle.
For jancsi; check for a drive belt that is close to failing. Your problem sounds like a water pump that isn't being turned as it should. That's why the heater works when you rev the engine, the slippage is less significant once the RPMs are higher.

Check for a cracked plug or bad wire. Make sure the plug wire isn't grounding out or leaking around the plug. Easiest way is in the dark with the engine running.

My 97 tahoe the rpm's start going funny engine startes running like its missing popping and ******* and die's it has new fuel pump ,sending unit ,rotor,cap.cam censor ,fuel relay everytime i c


I'm assuming you replaced the fuel filter when you did the pump.
You'll have to try to figure out if you are loosing fuel to the injectors or spark to the plugs to proceed.
Its possible something is failing inside the distributor among other things.
I'm also assuming you have checked the computer for trouble codes.

My 97 tahoe only running on 6 cylinders


If compression test is good is either no spark, bad coil or wire, or no fuel, bad fuel injector. Need to clarify which is not functioning properly.

Tahoe 97 Fuel problems


Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.

Missing while idel


It is probably a bad coil, have someone put it on a computer and see what cylinder is missing. The coils go bad all the time on the 5.4's
