Well i figured out my lean at idle issue. My o2 housing bolts backed out and i had a leak. I fixed that with lock washers. But now under full throttle my cel flashes and it feels a lil sluggish. I changed my plugs and checked all my pipes and vaccum hoses and they looked good. Any idea what it could be?

 

Not sure if its been flashed or not, but if thats the case then it might be knocking, triggering the CEL flash, resulting in the ecu pulling timing?

Just throwing it out there

 

^^ that. Tephra mod. Knock cell flash.

 

Car been tuned? If so it may have Tephra flashed where the CEL flashes with knock. If not, can you pull any codes? Could be a variety of things, MAF, Knock, etc.

 

Has been flashed and it does flash when spark knocking but usually only when cruising at low rpm. Once i mash it everything is good and it yanks. But now mashing it makes it worse. It flashes the whole time its mashed

 

Thr cel doesnt stay on so i don't get any codes when using a scanner.

 

You check your plugs and gap?

 

Put them in Wednesday and i gapped them before putting them in
