NEED HELP FAST!!!!spitting,stumbling low throttle

[ibspoolin2]

ok heres the new problem. The problem this started happening before my fuel pump went. when i drive at low throttle (20% or lower) it like missess,spits,or stumbels. when it does this it runs real lean it hits like a 16-17:1 AFR. the other day my fuel pump shit on my so i replaced it with a walbro 255. i just swapped it today and took it for a test drive and it did fine. but when i took it out the second time it was spitting like a *****. so i changed the plugs and it got alittle better it only does it alittle now but only when its warm. it is really pissen me off i cant drive normal. the things i already checked plugs wires timing changed fuel filter. and there is no check engine light.WTF i give up
Thanks Kevin

What did you GAP to on your car

NT 2.0 right?and what plugs u using.

 

[talon96tsi]

The only plugs anybody here should be using are NGK's.

i have bosh platuaim plus 2's im really bad at spelling they are gapped at .35

bosch plugs dont work very well in most cars other than european NGK's work alot better the bosch plugs have a longer reach into the cylinder than the ngks that could possibly be why your car is running rough

 

[Colt4G63 also]

I've used Bosch and Autolite double platinum plugs in my N/A 4G63, and 4G61; they performed flawlessly for years.

I noticed an immediate difference when I switched from bosch to ngk plugs.

There is no discussion on plugs for DSMs copper NGK plugs are the best out there and pretty much the cheapest too.

If NGK plugs are not available then you should find a different parts store, if you live in the middle of nowhere or need a quick fix then you should specifically look for copper plugs. Absolutely avoid platinum plugs and keep in mind that you will be absolutely wasting your money with iridium.

I've heard that's all true on a turbo engine. Since you have a naturally aspirated engine you can disregard all of that.

I run 2$ NGK spark plugs on both of my cars Turbo / NT.

And IF the plugs are not the problem on my NT they both work flawless.

Ps. I changed the MAF today and I will say that I have not noticed any problems on my 93 NT. It seems like this has fixed my problem.

+111111!!!

I think Ill still change my o2 only cause I know a guy that can get it for like 30 with his discount and it wont hurt.

Do you guys notice if you lift fast off the gas the car jerks just once?

I know in my 99 gsx My AFR goes to 11.0 to become very rich so that dosn't happen, but in the 93 NT It jerks everytime like it cuts out the fuel and chokes it or something.

THANK FOR YOUR POST!
