Spuddering Issues.. 3.8 V6

Skargon · November 20th, 2011, 01:22 AM

Welp, 1998 3.8L V6 with 101k Miles on her.

Spuddering a bit.

Replaced Plugs and wires, A few months back, No problems; Ran great.

Last week it started Spuddering while driving. Now it does it while Idling.

I Pulled the Wires and Plugs, Checked them all, Re-Gapped them and cleaned it all up.. Put them back in. Done, No Biggie.
Still, Spuddering.

Tested Coil Pack, it wasnt putting out good power, So I replaced it.
Still Spuddering...

I always add Lucas when I fill up my gas.
I always keep my oil at the right level, All Fluids Etc.
Just added a CAI and exhaust a month before this started Happening, Probably not the reason..
I've checked for Vacuum; Its got good pressure..

Any Other Idea's?

Probably going to my Mechanic on Monday.. Any Idea's would be great.

ALSO: Spuddering is at its worst around 1500-2400 RPM

Maybe its your fuel filter clogging up. Just a thought. Happened to one of our cars I was like wtf then I pulled the fuel filter and tried to blow air through it and hardly anything went through. I changed it and our problem was solved.

^ +1. i would change te filter and see where it stands from there.

Skargon · November 20th, 2011, 05:11 PM

Filter is Brand new. But I could always Pull/Check it anyways.. Good Thoughts.

Green_6er · November 20th, 2011, 06:45 PM

are you sure it's spuddering and it isn't just your clutch slipping?

Skargon · November 20th, 2011, 11:05 PM

The Spuddering is even at Idle in Neutral. Unfortunatly..

if you had a tuner I would datalog. Surprising what it will tell you...

Sputtering (we aren't talking about potatoes with spuddering are we? LOL) is usually caused by too much air/not enough fuel.

Do you have any exhaust leaks that could throw off your o2 sensors? Have you tried pulling them?

xtreme 2 · November 21st, 2011, 09:48 AM

I'd also clean the MAF with some dielectric cleaner... just to make sure it's not the issue.

Also, try unplugging the MAF while it's idling to put the system into open loop. Does this fix your idle issue?

Skargon · November 21st, 2011, 05:22 PM

It doesnt do it at idle that I can see when the MAF is unplugged..

Dielectric cleaner in the morning FTW anyone? Lol

clean you iat sensor, and maf. i had an issue last year, and did the following. replace the fuel filter, cleaned the tps sensor maf sensor and the iat sensor too. its working great. while your there clean/ install a new air filter.

Skargon · November 21st, 2011, 06:30 PM

IAT?

EDIT: Durp.

OH, Idle Air Temperature Right?
That is getting cleaned with MAF, Since I know its there.

Skargon · November 21st, 2011, 08:46 PM

Cleaned them Both with MAF cleaner I just bought tonight to do so.

the MAF needed it BADLY.. The Silver wires were black..
Car runs better except for the Sputtering. It's even worse now.

it HAS to be an injector Or Timing...

roth515 · November 21st, 2011, 09:02 PM

Vacum/header leak? It is getting colder and metals are condensing, would be more noticeable?

Skargon · November 21st, 2011, 09:04 PM

Well, The past few days it has been a Mix of 40 Degrees all the way up to 70 and even nearly 80.
It does it the same no matter the temperature.

ANYONE, Who has Editing skills.. Try to Point out where the Crank Position sensor would be on my car or explain it in detail?

This is my last try before I hit my mechanic tomorrow..
