Ok guys here is my problem! I recently had the TSB done for my 08 5AT Coupe cause it died many times and had the dealer take care of it asap, now it's been 2 weeks and all the sudden it starts up and idle drops way low and dies What could it be now? Dealer changed out Battery and the Vent valve thing that was causing Battery to drain, my other concern is the engine ! Has anyone experienced that sucking noise from intakes after tapping gas very fast it's like the idle takes time to respond to gas pedal and I here that sucking intake noise from intakes , only problem is I have OEM intakes w HKS drop i'n filters... Maby it's just me being paranoid but after Engine started shutting off I been wondering if it's related w Intake system or what... Car Fires up Fast most of the time but last night for example, it took 3 times trying to start it for it to fire up.....

 

Again? What's happening to your car?

 

It dies for some reason ! I don't know man , just need HELP!!!

 

Your problem isn't common, just take it back to your dealer

 

I will on Monday I'm due for oil change anyway...

 

Yup dealer time...sucks bro

 

Maby i fuked up my starter trying to start it whenever the battery was dead dunno but if anyone had experienced my issue please chime i'n.

 

starter does not sound like the issue from what you are discribing

 

yeah noob! STarters are only use to start your car. It won't make it stall hahaha.

 

my friend have a old merc cougar which was having alot of similar problems. Try cleaning the Throttle bodies, cleaning intake filters ect just all the small things, if you really want (depending on the milage) change your spark plugs. first take it to the dealer

 

I remember Q8drifter mentioned something of the Throttle bodies and since I ordered New R2C intakes I will def Clean them since i'n at 49,000 miles... Def a great idea since I'm sure this may cause the weird idle drop.

 

Sucks bro.. Wait on putting those R2C in until the dealer figures it out.

Last couple days my car has been cranking slow in cold weather. I wonder if itsthe TSB, I drive my car daily so I doubt it has enough time to full kill the battery overnight. I bought the car with 6k miles on it and am unsure if the tsb was ever done. I've now got about 17,3xx miles.

 

that sucks! I hope they fix it.

 

Yeah I think it's the throttle bodies needing To e cleaned. Already had TSB done for Battery , what else coif it be?

On a side note , I crushed my bran new Fast Intentions Left muffler, now thinking of selling cause a new one is $400 shipped and can't imagine this happen again if I replace and it gets hit again... Caused pulling into my wrk garage check it .


As of now I'm debating on selling or just replacing and being extremely careful but I just have had my second issue w the dam mufflers , first my CF got FD now these beuties after two weeks . Can't imagine paying another $400 and I have another accident for the 3rd time...




Sounds fine and performs same but Damn !!!

 

I scuffed my CF mufflers once when I had FI. It bugged me and its part of the reason I sold it. That sucks Diego, sounds like you're having some bad luck!
