Motor question
OK tonight after getting the back from having the steering rack replaced and the car is now being driven everyday after sitting for two weeks it has devolped a sputter but only under 30% or more throttle while accelerateing. I punched and it just sputtered like no tommarrow and then backfired. Any ideas whats going on. It had under a 1/2 a tank so I then dilled it up and seemed to do well but will only do it after 30 mins of driving or so. It had also completely shut down when I got of the freeway.

That was replaced along with the waterpump at 77k miles. It now has 146k as it sits today so that could be it but I don't want it to be.

I did have that e10 crap in there then I filled up at bp which doesn't have that e10 and it runs alittle better but is still sputtering. What should I look for in the injectors.

I don't know if this is your problem or not but, the multec injector is not alcohol complient. The design of the injector has a epoxy seal that seals fuel from entering the coil housing. once this seal is broken the coil gets contaminated an eventually will fail, it might be already failing. You should check the injector coils with an ohm meter. the readings should be between 12-16 ohms with all 8 about the same. If you got some weak or shorted coils replace the injectors. There is no test that you can do on the injector on the car but this. Good luck!

but those injectors are not tolerant to ANY fuel injector cleaner. When the seal goes the coils will get contaminated and the injector will fail. Just keep your eye on it. You should really do a ohm check to see where you stand. These injectors have 146,000 miles on them.

Do you get any codes if an injecter is bad - or do you just test as you said....
I've read a lot about them on the forum doesnt seem to be the same answer twice other then check then with ohm meter
- my 95 and 01 run great but always wonder about the injectors 48k on 01 and 68k on 95
Thanks

Injectors were fine. It was bad gas. This new gas that has 10% ethanol in it was the issue. You would think letting the car sit for 2 weeks and starting it up would keep from having issues. But the ethanol separated from the gas and fouled out the plugs. Go figure. I hate this ethanol crap.

Back fire does sound like a spark problem...

Have you checked your plugs? Sounds like fouling to me. Cleaner may have helped just enough to reduce fouling for now.
Also, there is no evidence that E10 damages anything. It has been studied more intensely that any other fuel in history. Even E85 is hard pressed to show any wear or problems. Granted, even if the injectors work perfect, there are no vehicle computers that actually run ethanol properly, FlexFuel or otherwise. We run E20 in MN and no service center has ever logged an issue with it.

Ethanol does not separate. It is just like IsoHeet. Fully disolves.

Here in Florida our gas only contains 10%. Is what i meant was the ethanol separated from the 93 octane. Which I believe was the cause because doesn't Ethanol contain water, so that is what separated or it may have been bad gas from the beggining and it only took a matter of time to cause an issue. But I hear alot of ethanol giveing motors problems especially if it is a boat motor. Gas does go bad if it sits regardless of ethanol or not my experience is the ethanol just spead the process up.
But what they put in the gas, AND CALL IT ethanol is a toss-up.
