Please help!

1998 Cobra. No tap/rattle on start up. Starts when warm. Mostly between 2 & 3k, under load goes away, deceleration goes away. Mostly heard at cruising rpm and acceleration from a stop going through the gears.

Not good...… If I understand correctly you have a tune in the ecm….if so 1st, put it back to stock, clear all codes in the ecm and erase the ecm's memory. If still there...… use either a mechanics stethoscope or long screwdriver placed against your ear to help narrow this down...

What aftermarket parts are you running? *just* the Bama tune?


I have not heard many good things about them. If you're running stock parts, there's nothing about a Bama tune that you want. Even if you do have aftermarket parts, those guys are clueless shysters. They couldn't find a proper tune if you locked them in a room with a marching band, AC/DC and Gwen Stefani, all playing "Mary Had a Little Lamb".


They are far more likely to damage your engine than have any significant beneficial effect.

I smile a lot. It makes people wonder what I'm up to...

I don't think it has something to do with the tune because a tune doesn't go bad in just one day, but I still recommend that you send to Bama data logs. They may be able to see the cause(s) of the issue through the logs and often it's not tune, but something else that needs to be changed
