This all started a few days ago as I head out on a date with my girlfriend I notice a define power loss cel comes on so I limp it to autozone and replaced one of my coils and all was fine again or so I thought now when I drive it if its cool it runs great but going into boost after it warms up it sputters badly I definitely am still making boost. Could the other coil be defective or is it possible I have a bad replacement coil cel is off now. Car is mostly stock just bolt ons cai fmic exhaust bov wg. Running 7psi

Any help would be great

Thanks
 
Not too long ago took out the ngk plats for some ngk coppers I'll try that and report back how often these things crap out the previous owner had already replaced them at one point (found receipts)
 
You likely need new plug wires and coil boots. Make sure the plugs are gapped correctly to .028-.030".
 
Probably do need wires the look original the plugs have been in there for awhile 6 months at least I'll check reset the gap if all else fails
 
Turns out it was merely a loose plug wire all is well again
I will be replacing the wires anyway tho as I already ordered some ngk wires
Thanks
