Hey you all, new to the mustangs and this forum.. I used to be into boosting Hondas, but u can only get so far doing so.. So I've Always have wanted one and now I got one and im in love, it's a 97' GT automatic, with new gears 373 (idk if that's right correct me if in wrong,rebuilt tranny, cold air, no cat, and flow master exhaust.. It has a SCT tuning software and I need to learn more about that..

But it keeps dieing when I put it into reverse or drive, maybe it's in the tune? Or what else could this possibly be.. And again; I'm new to this so sorry if I put the wrong thing down.. Thanks in advance for the help!!

If u have any knowledge on the tuning software, please inform me with anything u can tell me.. Thanks!

Anyone?

AlsCobra

Well try putting it back to stock tune first. Is it idling really low or running rough? Surging? Needs a little more info.

GTpowerwithin

It idles a little rough, but low.. I'll try it but is it hard to do the tune?

AlsCobra

Tuner should walk you through it. It's not that difficult. Otherwise low idle might be IAC. Dunno man.

cdynaco

vacuum leak?

AlsCobra

Could be. Dang auto trans! Could be all sorts of crap.

GTpowerwithin

Man, well I try an go back to the stock tune and see how it runs... And I'm gonna change the spark plugs and change the oil as well..

GTpowerwithin

I guess the tune is set up for 91 octane gas... But if I tune it back to stock, will everything run fine? And I can just get regular gas?

AlsCobra

Just put it back to stock and see if it will idle. Just to make sure it's not a tune problem.

GTpowerwithin

Ok, but how to I put it back to we're it was?

GTpowerwithin

Like if I do a stock tune, how do I out it back to the tune I recently have been on..

AlsCobra

Just follow the prompts on your tuner man. Should at least 2 tunes stored in it.

And I guess the guy that got gas for the car said he got ethanol, and when he did he forgot he didn't use any ethanol, and it started dieing on him when he did get that gas..

GTpowerwithin

Correction: He would use non ethanol on it and it never died, but since he put ethanol in it to sell it, it started dieing..

When I first read this today I thought converter lock up myself, or vacuum leak, or....


what is the ethanol ratio? you may have to drain teh tank and start over to rule it out.

GTpowerwithin

Idk know the ethanol ratio, I don't understand, lol...

I know when I put it in gear, the battery gauge drops..
