hey guys. 95 talon tsi awd misfires badly at boost. ive changed the spark plugs/wires. thinking it could be the ignition coil, what do you think?

may also want to try swapping out the ignitor/power transistor.

could be a tuning issue, do you have any datalogging equipment?

Id test the coil and power transistor. Did u gap the plugs and put the wires in the right order.

platinum plugs. didnt need to be gapped. and yes the wires are in the right order.

I had ngk platinum plugs in my 97 gsx, stock, and it didn't run too well. I bought ngk bpr7es' a couple weeks ago and accel wires and it runs and idles like money now, misfiring issues gone. Except I still have some sort of lag on spool up.

Somewhere along the line I've read that platinum plugs are a big NO for DSMs. As to why, I have no idea. I wish I knew, anyone care to enlighten?

Anything other than the oem NGKs are a big no.

Didn't need to be gapped? Did you check them atleast to make sure? I would never trust that especially with a boosted car. Check that first thing before you go buying anything else.

I would get some NGK's anyway though, I have heard the platinums suck in DSM's too. If you are not running over 16-17psi get the BPR6ES though, the BPR7ES are more prone to fouling and are not generally needed unless you are running higher boost.

Oh yeah and Sway, pleast list any relative mods you have on your just if any. It will help you get answers. This problem will most likely be something really simple though.
