Regap your plugs to .8 stock is 1.1

while you @ it. wrap your coils with electrical tape so spark wong jump off.n clean the tips of the coil. could be dirty inside.

clean your MAF (could be dirty and causing that) Just clean the damn thing it will help. Trust me!

check your grounds!!

*nxt time search is your best friend. then post after doing all that reset the ecu.

I gotta do the same tomorrow.... (i've been saying tomorrow for the past 2 weeks)

mine is breaking up @ high RPMS if I floor it around 5,6k. i need to regap my plugs and pretty much what i told you to do LoL

tomorrow though

oh and for the dying part, good Question. mine is doing that too but my HKS is not Recirculating. so thats why.

if its dying YOUR CASE could be a VACUM leak..
