I have an AEM EMS just tuned this June by Sean Ivey. Now the car was sitting for about a few weeks but it started to sputter before sitting. Now I started it up yesterday and the car sputtered BAD! I believe it is due to a drastic change in the weather. Do I need a retune? Will it fix itself with driving? Any help? I really didnt want to spend another 600 on a tune.

Thanks,
Jim

 

It will not fix it self. I would first check plugs. Then get with Sean ivey he is a really stand up guy and should help you out.

 

What are your mods also?? but start with plugs for sure...could be simple

 

50 trim, all the bolt ons. Ill check the spark plugs first thing. If not ill shoot Sean Ivey a call hopefully he will help me out.

 

check the plugs and if thats not the problem you most likely need a retune because of the weather change

 

You shouldn't need a retune because of the weather. You might need to touch up the warm up enrichment. Once the car is fully warmed up, it should be the same as before.
Like the rest of the guys said, check the plugs. Was the sputtering on idle before you parked it?

 

Call the shop and make an appointment to come in. We will look it over. The weather change is compensated for, maybe something else is wrong.
