Possible Pulley Problem

[RedFireCobra]

thats a big no no to change set-up after a tune ! Termi motors are very sensitive to change, especially when changing around the intake setup. You are running way to lean from the sounds of it. Get a tune asap !

PS - Make sure they clean u'r mass air sensor and line it up rite before the tune

I hooked it up to one of my buddys computer and the following came up..

P0602 Control Module Programming Error
P0507 Idle Air Control System RPM Higher Than Expected

What was weird was my air intake temp sensor was reading 140+ and the spark advance when accelerating slowly was reaching upwards of 50

PPRV Delete Kit?

:smash: Hello....are you listening?

:smash: Hello....are you listening?

Haha yes i'm listening.. I was discussing it with the guys over at svtperformance.com and they said the hesitation is common and that the PPRV Delete Kit will resolve that.. I know i need to get a tune and i'm going to.. But the tune isn't going to fix the hesitation..

There's guys having the exact same problem i am and the tune did nothing for them.. It was the PPRV Delete Kit that fixed it.

Usually you get the hestitation between shifts when the PPRV is a factor. Either way, removing the PPRV is a good thing.

As everyone has stated up above, get a new tune first to ensure you are okay at WOT, then go ahead and remove the PPRV.

Alright.. As much as i want to take it to Mustang Magic i'm not really feeling the 6 hour and 41 minute drive.. I contacted Kennedy's Dynotune in North Tonawonda, NY..

sorry, your initial description was that it was misfiring and the plugs looked like it was running lean. I didn't see the hesitation post, :smash: on me, lol

...Once in a blue moon I get a hestitation shifting from 2-3 or 3-4, where's the PPRV (any pics) ...how do you remove?

ohhh so u dont have a tuner? How was the last tune done ?

Was done before i bought it.

U might have a sct chip on u'r computer, i would check and make sure u dont have one before going further

Not sure what you mean.

Okay so i'm confused.. I'm trying to figure out what size belt to buy because There were idler pulleys installed on my motor and i'm not sure if they're 90mm or 100mm i measured two of them and would it be possible if one is 90mm and the another is 100mm because that's what they measured out to be? I'm going with a 2.80" upper pulley.

They are D'agostino Idler Pulleys

How bout a pulley swap..? I would say on a scale of 1 - 10 of being handy i'm about 5-6.. Do you think i'll have a problem doing the swap myself or should i just let Kennedys do it?

...thought you have a 2.80" pulley!? ...can't go much smaller!


...Not hard to change at all, FYI, with the right tool!

No i don't have a 2.8 pulley.. I have the stock one.

 

[Timspony]

Not sure what you mean.

You would have to pull your compter out of the kick panel to see if it has a chip attached to the computer (did this with my Cobra when I purchased it!)...Make sure to disconnect the battery first!!

Sounds like you'll need a 74" long belt....I'm running Metco Idler's with 90mm Aux. & BF 2.76" pulley with a K080740 (74") belt....I ran a K080745 (74.5") belt when I had the 2.93" pulley...

 

[SubZero00GT]

74" for sure?

Below is a quick reference guide:

• Stock Upper Pulley-75.0"
• 3.00 Upper Pulley-74.5"
• 2.93 Upper Pulley-74.0"
• 2.80 Upper Pulley-73.5"
