Thread: engine hesitation/ missfire at wot

So i was on why way to wrok and stepped on the gas and all of a sudden i had a hesitation and high kr! i have stock pully btw. it run fine when not in boost but as soon as you bring it to wot it misses and hesitates, any ideas whats going on? i just installed plugs about 3 months ago and wires just yesterday. at work i took a quick look and found a vacume hose cracked and though i had my problem, did a quick wot down the road and all ok! then on the way home same problem! and no hoses bad that i can see! sorry for the long story!

Do you have anything to scan with? A bad oxygen sensor can cause these symptoms. When did you last change it?

Just a guess but it sounds like your running lean. I’d start by re checking your wire install, look for stuff you may had disconnected or damaged. Then I’d take some carb cleaner or propane and look for vacuum leaks. Good luck

no i will have to run to autozone and see if the car stored any codes it doesnt trip any ses lights or anything though so i dont know if im going to get much help from the brain lol. can only try i guess

Could be a cat starting to clog up.

well guess im not going to have my gp in the dells have to take another car. have a new cat and headers ,waiting to get put on when i get back.
