i think i have a fuel cut issue?

[kazdombrowski]

Hey guys ive looked and looked at some posts up here and i cant seem to find whats up...

history= 95 talon tsi awd. bone stock minus carbon fiber hood..

I was on my way to advance to get some oil today with a buddy of mine thats back from college and i was in 3rd around 5k-6k rpms and about to shift when bam! my car decided to buck a couple times, i shifted into 4th and everything was fine..

I've read about it being boost leak or plug wires, but i just replaced my wires, and i did a boost leak test and everything was good... should i replace my plugs?

Where was your throttle when the bucking occured, WOT, or were you decellerating before disengaging the clutch?

Any tuning devices?

You may want to check your wastegate actuator to make sure it's working properly.

WOT (it happens in the high rpms in 4th gear also just found that out), it was literally like a second before i was planning to lift my foot to shift haha.. i have no tuning devices.. and how would i check the wastegate actuator?

could it be over boosting maybe and hitting cut?

Sounds like a boost leak and fuel cut. Did you happen to section off your Boost leak test to just the charge system and then the intake manifold/other stuff?

Also, check your fuel delivery. When's the last time you've checked your fuel filter?

No boost controller? Stock boost I guess I should ask?

If you have a MBC make sure you check the lines for any rips.

He says it's all stock, but I figured I'd ask. I'm not sure that there's such thing as a stock DSM anymore.

I would check the wastegate, fuel filter, plugs and wires.

I get the same thing on mine but it will do it in other gears as well when wot. I have a set of accel 8mm wire on mine that was installed by a previous owner. Anybody running them without any problems. My other dsms I ran magnacore and never had any problems.

 

[kazdombrowski]

would my biss screw being stripped have a contribution to this? and how can i tell if my plugs are fouled out? and any suggestiions or comments on bosch platinum spark plugs over ngk? or not.

 

[GRAVEDIGGER]

Here's a good reference chart to help diagnose your spark plug conditon.

I would get a new set of NGK BPR6ES plugs if I were you and you should change the fuel filter too if it's been a while or you don't know the last time it was changed.

 

[kazdombrowski]

thanks for that link ^ and yes i just changed the filter maybe 100 miles ago
