delay/misfire?
 

97 Gst,

my car was throwing a check engine light... took it in to get fixed because i couldnt figure it out. They told me they couldnt figure it out so i went to the internet to start searching. from what i could tell it was the IAC valve.. so i cleaned it and cleaned the throttle body while i was at it and i cleaned the MAF sensor.. check engine light is off and has stayed off but now it feels like there is a delay or probably a misfire. when i accelerate the car feels like its skipping a cylinder.. any suggestions? ( wasnt doing this before i cleaned everything)

Never hurts to replace spark plugs and wires.

i have msd wires and ngk plugs comming in today hopefully.. i just wanted to see if anyone had any experience with the same issue and if anyone had any other possible fixes.

Boost leak?

ill double check what i can here, but i was pretty sure i got everything back together tight.. the thing is when im at a higher rpm it doesnt do it and when the engine is warmed up it doesnt do it... i got my new wires and plugs so ill let ya know if that fixed it. does anyone know a good gap for the sparkplugs? remember im basically stock

.030" is what I always ran in stockish DSM's.

alright , i have them gapped around .28 to .30 so i should be good then

Re: delay/misfire?
 

so far its helped but it threw the timing off a little.. ill run it for a bit and see what happens
we'll see what happens in the morning when she's running cold

Re: delay/misfire?
 

alright so it started doing the hesitation / misfire again since i put the new wires and cables on.. i made sure i set the gap and i have gone over the engine and im pretty sure all boost leaks that are a 5 min fix have been taken care of.. any other suggestions?
