My car seems to have problems starting sometimes, its like the battery is getting old. It manages to start put it does not seem to fire properly. It feels like it is only running on a couple of cylinders or something. If I rev it a little, its really shakes the car and drops low in the revs.

To fix it, is just a matter of turning the car off and then on again.

Think its just the battery getting old?

not the battery buddy

Damm it, I just had it serviced and retuned last week. Do you know what it is?

What mods do you have. Let us know as it will help us answer your question

idol mixture out?

Piggy back computer from RDP, redback cat back system. K&N air filter.

Piggy back? Do you mean Unichip? That could be your issue...

Was the car doing this before you had the re-tune? I'd be checking Coil packs and spark plugs too.

I'd say he's talking about RDP's own piggyback...and that's where I'd be pointing the finger too.

Yea it is RDP own piggy back...
