WnR24VTT Posted May 20, 2012 Report Share Posted May 20, 2012 I have a 2010 sho with 11000 miles and just put the stg3 tune in from livernois. The problem that I have is when I'm wot in second gear the check engine light come on. It just flashes on and off till I let off the gas then goes away. It only stay on once and I was able to pull the code from the sct tuner. The code was P0303 cyl 3 mis fire. I put the car back to stock and car works fine. I checked cyl 3 plug and looked just like the others. I took that plug out and put the plug in cyl 6. I wanted to see if that plug was bad to see if I would get a new code like mis fire cyl6. So I put the stg3 tune back in and went for a drive. Same thing with the check engine light just flashes on and off in second gear then goes away when I let off the gas. This time it wont stay on to pull a code. I try to pull a code when its flashing but the tuner say no codes. Any help would be great.

fishrising Posted May 20, 2012 Report Share Posted May 20, 2012 Contact your tuner, both Torrie and Rick have excellent customer service! You may even be surprised how quick they return an email. Link to comment Share on other sites More sharing options...
WnR24VTT Posted May 20, 2012 Author Report Share Posted May 20, 2012 I did e-mail Rick. Got the tune on Saturday and by the time this stuff happen they were closed for the weekend. He should send me a e-mail back Monday. Link to comment Share on other sites More sharing options...
fishrising Posted May 20, 2012 Report Share Posted May 20, 2012 Skip 3 and go for 4 or 4+, it's only a matter of time anyway! And see what happens... Link to comment Share on other sites More sharing options...
bpd1151 Posted May 20, 2012 Report Share Posted May 20, 2012 Hhhmmmm..... sounds weird for sure Even the boys from LMS are entitled to a day off here and there..... Rick is VERY responsive though, and I'm sure Dan would even be curious as to wth's going on..... But this is the 1st I'm hearing of any issues (with a tune) yet alone one such as you're experiencing/describing. Assuming that is the tune is the basis of the problem :noidea: BTW, I noticed in your sig that your curb weight is listed as 5,200lbs..... you are aware that our SHO's our between 4,300 & 4,400 right?

EcoBrick Bob Posted May 20, 2012 Report Share Posted May 20, 2012 Pull the plug again... Turn it right side up and then upside down... See if the center ceramic piece slides up and down on the electrode... If it does... you have your answer. Solution: NEW PLUGS - Update to the current plug # from the ones that were original in most (maybe all) of the 2010's. I had this happen on my #6 (306 code). It would flash when it mis-fired. If it codes... it turns solid. Until you solve this issue... DON'T do anything like installing a higher performance tune. I would keep trying to get a code with the old plug in the new cylinder position at this time. Another possibility is "BAD GAS"... I know it sounds like a broken record, but I had a coding issue with the latest strategy stock tune, on the way back from FL... I was running BP 93 and got flashing and eventual coding 3 times, with about 60% of the tank burned off. That was 2,000 mi ago... NO CODES SINCE! So... first I would check that plug, perhaps after it codes again with an actual code you can read.... and if it's the same plug... you likely know you need new plugs. If it's the same cylinder... then it's bad gas... or????? PM me or e-mail me if it's the same CYL. Whose tunes are you running??? Link to comment Share on other sites More sharing options...
larrylu Posted May 20, 2012 Report Share Posted May 20, 2012 Why not try your stage 2 just to see what happens. It is supposed to be identical to stage 3 except for the torque management which is supposed to be reduced in 2 and removed in 3.

fueld13 Posted May 21, 2012 Report Share Posted May 21, 2012 Shoot, I hope it's nothing serious! I'm excited to see you're quarter times with a 4+ tune at 5200ft! I'm in salt lake city, about 4400ft. Good luck! Link to comment Share on other sites More sharing options...

EcoBrick Bob Posted May 21, 2012 Report Share Posted May 21, 2012 My latest guess is bad fuel.... It would be pretty hard to run lean at 5,200 ft. What is the plug number that you are actually running? You can get a new set of Motorcraft plugs from Rock Auto for around $25. You want to use the Number that shows up for 2011, and are the alternate for 2010. Ford's TSB on this either changes the plugs & or puts a different strategy tune into your ECM. But.. they have to see a code to be able to do anything. Link to comment Share on other sites More sharing options...
WnR24VTT Posted May 21, 2012 Author Report Share Posted May 21, 2012 Just got home from getting the wife from work and it did it with the stock tune in. Could be bad gas. Will have to wait till the tank is almost out till I fill it up again. I'll order new plugs 2 since there cheap. Thanks for all your help. Will let u know when its fixed and how it got fixed.

EcoBrick Bob Posted May 21, 2012 Report Share Posted May 21, 2012 We trust the gas stations octane #... but we have no idea if it's accurate, or how long the fuel has been in their tanks. Premium is purchased less often, and is affected further by the station's price differential from their most popular grade. Gasohol ( 10 % alcohol) degrades/separates, that's why the alcohol is shipped to the tank farm, where it is blended into your fuel. It's possible that that tank you get or got has been in the ground for several months. That's why I buy my fuel from the busiest vendor, which is usually not a NAME BRAND station, simply because (in my opinion) their fuel is the freshest. In FL, it's usually Costco, on the hwy, a Pilot or other truck stop type vendor, and here in IA, Murphy (at Wal-Mart), where yesterday, they were selling 89 octane for $3.22! 93 was $.25 more.

Livernois Motorsports Posted May 21, 2012 Report Share Posted May 21, 2012 The first thing our tuner said was could be bad gas. We didn't see anything wrong with the files and all files are identical with exception of the strategy. I did however send 2 new files today in case something happened when they saved. Please give them a try and let me know if you still have issues. Thank you, Rick Link to comment Share on other sites More sharing options...

WnR24VTT Posted May 22, 2012 Author Report Share Posted May 22, 2012 Got the new plugs in. There not the stock replacements [could not find any in town] but there the same as what bpd1151 is running ngk 6510's. Test drove the car with the stock tune and no more flashing engine light. Will put the stg 3 tune back in after dinner and hope for the best. Link to comment Share on other sites More sharing options...
EcoBrick Bob Posted May 22, 2012 Report Share Posted May 22, 2012 Those plugs are colder than the stock plugs. I would ask Rick it that's a good idea at high altitudes.. I have no experience with which plug heat range is best for your area... but if you take it in for warranty work with non-Ford plugs, you may have an issue depending on your relationship with your service rep. Which plug # was actually in it originally? Since there are Ford TSB's regarding plug issues on 2010-2012 EB engines, I have stayed with the stock suggested replacements. Just my 2 cents... and I may be totally wrong. Link to comment Share on other sites More sharing options...
