Low rpm?

[Cone Sweeper]

Ok.. Start with this, I have a Steeda intake, xpipe, mufflers, CMDP ( from steeda ) and got a tune a month or so ago. Not a single issue. Weather has been changing a bit down in south florida ( Nothing huge but at night it gets a little chilly - low 70's to high 60's from it's normal 80's lol ).
Went into work today and drove normal on the highway, little bit of getting on it through traffic but that's it. Stopped by starbucks to grab a drink for work and came out and started the car.. idle's up then falls to 400rpm's and sits there. Doesn't move up or drop much more then that. Put it in reverse slowly letting out the clutch no bucking or anything no idle drop what so ever. Drive less then a mile and come to a stop light and same thing.. falls down to 400rpm's and sits maybe moving down a little but car didn't die. I shut the car off and restart it and idle sits at 700 and doesn't budge.
Now.. did the same on the way home. Parked the car and let idle and sat at 700. Turned the car off and back to 400 idling lower.
NOW lol. If you got this far.. do you think it's the TPS taking a shit on me or tune related or what?

thanks for any help!!

Bump..anyone have any ideas?

Best bet would be to start off with the basics....clean the throttle body, clean the MAF, if it hasn't been done recently(although probably not the issue) change your fuel filter, and unhook your battery for at least 20 minutes to reset the KAM(keep alive memory) so the car will re-learn it's idle and low throttle fuel trims.

Yeah the FF was changed a couple months back, TB and MAF recently when i did the CMDP lol. I'm kinda driving myself up the wall here.. I'll try unhooking the battery idea.. didn't think much of doing that. And see if anything comes of trying that.

It could also be a tuning issue. I know I was having an issue with my tune after I installed my e-force blower where the idle would drop real low, nearly stalling, and then come back up. If the tune doesn't account for the changing temperatures it can have issues.

If the battery reset doesn't work, reach out to your tuner and he may want you to do a few datalogs for him to review.

you call paul yet?

 

[Cone Sweeper]

Yeah i spoke with Paul. He said it could possibly be a vac. leak but that would cause idle to raise not drop. Then said it could be the TB or TPS as a possible issue.
But He wanted me to drive the car around and repeat what happen last night. Drive for a bit, then shut the car off to see if it does it. And well.. it didn't. Between letting it idle for 20 minutes infront of the house and then driving for 15 or so .. then doing the same on the way back. Nothing happened. I don't get it lol

Any idea's of what this could be? or just a random hiccup possibly?

on a related note..did you recently add anything to the mix mod-wise? maybe you recharged your air filter and put too much oil on it? Prolly something very simple like that.


We gonna do lunch before I move? Hundy? LOL

Sounds Like a tunning issue
