Car bogging out when I hit the gas...new thing

[jschreiber]

OK so I was having issues with my car at idle while in gear. At a stop light or something, it would suddenly drop idle real low almost like it was gonna stall. No issues when I hit the gas, just at idle while in gear and neutral.
So I started with easiest stuff first. Checked lines and hoses and all the intercooler piping. All seemed fine. So then I changed the spark plugs out and bam, fixed the idle issue. Well soon as I go to drive it, I hit the gas and it sputters and has a rough acceleration. It goes smooth for a minute and then chugges out again.
This is really only under hard acceleration though. If i go slow and steady its fine for the most part.

So what can it be? wrong plugs? I changed the wires and that didnt do it. Maybe MAF is bad? Fuel issues all of a sudden?

What plugs did you use and did you check the gap?

Sounds like your plug gap is off. Double check all of the plugs and go from there.

no didnt check the gap. Thought they were pre gapped. They are bosche plugs

Bosch plugs aren't really the best plugs for out cars. NGK's are definitely the best. Pull the plugs back out and see if they are fouled at all. And while you have them out, gap them or consider replacing with NGK BPR6ES plugs and gap them also. I would also do a boost leak test if it's happening under hard acceleration, a.k.a. building boost. Try these two things and if it still happens check your MAF sensor.

I second the NGK bpr6es. Never had any luck with Bosch on these. Our engines like the plain old NGK plugs and fresh ones at that. Gap em and keep fresh ones in it for the best outcome. I don't mean replace them every time you turn around just understand the amount of heat they are subject to under boost and learn to read your plugs. They can tell you a lot about what's going on in your engine. Now aside from that what plug wires are you running. They can if faulty give the same symptoms.
