OK, my turn to ask a car question.

Just a quick update.

The problem resolved by itself.

Didn't have to replace the idle air control valve or even clean the throttle body.

Did the relearn functions on anything I could get access to with the scan tool and no more idle stumble. Car never ran better, even when new.

Thanks for the help. I am sure the idle air valve will need replaced someday, But not today. :)

Not too many Top Gun quotes from the latest movie. That's the only one I can think of.

The car is crazy fast now. I feel the need, the need, for speed. :)

If it resolved its self, could of been due to a relearn. Any chance you had a jump start or new battery/reconnect battery right before the problem started?

Dirty throttle body and memmory wipe = base idle opening for throttle body is reset.

A bit of driving and it will relearn after a bit of driving.

The amount of data this scan tool gives is mind blowing.

Fuel pressure actually is provided if I recall correctly.

It gives an incredible amount of live data.

I never had any codes, it was just me noticing a stumble when stopped at a red light. For a dongle costing under $100, and containing full data for all vehicles (free for the first year), it is pretty impressive.

Basically does what the expensive $5000 scan tools used to do.

Maybe a bit more poking around to find the various features, and it has to use your cell phone as the display and interface.

I only bought it to confirm that the coil packs were having issues before replacing them.

The bi directional features are amazing. Send a signal to turn something on or off and it happens. Not sure what all it can do. But it is a LOT more than I expected.

I should carry it around in my pocket. If someone's car has an issue, I can just say, "Excuse me while I whip this out". :)

Oh, i read the title wrong. I thought you wanted to ask a car a question. I was going to let mine give it a shot.

I have no idea what you just said, but more power to you! :)

Seafoam is great stuff. Never tried it on a car though.

Crap fuel.

Probably related to too much ethanol.

I'd suggest changing your fuel filter as a start.

The filter is probably not the issue, if there's a blockage, it's due to combustion of shitty fuel...I have proven to my son, on our 1000 mile trip starting last Monday, that premium fuel is the best simply because it has detergents in it. The service engine light came on after he started using cheap fuel, and on the trip I asked him to put premium in it...After about 30 miles running premium from a tank on empty (6 miles left) the light went out and stayed out...Now he believes me...

All gasoline has detergents in it. All premium fuel does is makes your wallet lighter, unless you have a high compression engine that requires it for the higher octane (anti knock) number

The higher octane does eliminate ping and knock, but there are more and better detergents in premium...there may be SOME detergents in cheaper fuel, but not as concentrated or as powerful...Gas never hurt my wallet, but it has extended the life of engines and fuel system components...

I just channeled, it’s said use a fuel additive or use better fuel for awhile.

Premium burns slower and cooler, will promote carbon build up in engines not designed for it.

If it was a fuel filter issue, the vehicle would starve for fuel at high rpm. It doesn't, this was an idle issue.

Which was cured about a page ago by the way.

I see another video saying to clean the throttle air intake.

I bought the little CRC spray kit last year and cleaned the MAF sensor which helped the engine run better, but I didn't bother with the throttle intake. Maybe I will do that as well.

The detergents are the reason it cleans out the deposits...The detergents are why I put it in everything, well except my Diesel lol

If you want to believe that, far be it from me to change your mind. Take pics if you ever pull a head. Better yet, get an endoscope.

Thanks

Me, it wants an email etc. Never mind.

Seen more than my share of engines torn apart, believe what you want...I have had this car for over 30 years and never had to tear it down...I have no issues with taking it to the red line...

Belief can be a powerful thing.
