Alright well i was driving home today and noticed a weird noise coming from under my car, i could really hear it when i got next to a building because of the sound bouncing off the building, so i got home and popped the hood and it sounds like it is coming from under the supercharger, then i went around to the rear and listened to the exhaust and it wasn't smooth sounding at all, there was like a little putter in it. Has anyone every heard of this, or could anyone tell me whats going on, I hope my description is enough for someone to help me with.

Thanks
Rich

 

take it to your dealership for warranty work.

 

ya, I get that putter noise when my car is idling at above 180degrees. It putters about once every 10 secs. don't know what it is. The car runs fine though.

 

Mine is always puttering. If it is what i'm thinking of, i thought it was normal for our cars to do this.. Like the exhuast sounds really "off rythm" thats the only way i can really explain it...

 

nah its not normal ..mines purely f'd since i bought the car..i only recently found a dealership that believed me when it finally did it for them other dealerships i don't even think heard it even though it happens almost every time and told me it was normal..trust me..its not..far from it

 

Were they able to fix it? What was causing it?

 

im going to bet my money on the SC blades, do u have a new pully or any work done?

 

what the hell did they say was wrong then?

anyone else have this happen or know what the problem is?

Mine did this when I bought it brand new. So i don't see this being an issue.

 

nope im still going back...tues again infact...they can't ifgure it out..they've replaced = spark plugs/ spark coils/ injector 0-rings/ injector sleeves/ again spark plugs and again coils...they were thinking maybe they were just bad stage 2 injectors and i told them it was like that even before stage 2 (which it was) so can't be the injectors...oh and some vacuum hose was rubbed through so they replaced that (but if it was as simple as a hose i wish) who knows what they're gonna do next

send me a sound clip or something of ur car and i'll try and get one of mine aha

 

My car rruns rough when the Radiator Fan kicks on which is always above 195 or so. I know our motors are naturally noisy though. I mainly hear the lifters in my motor working.

 

Maybe your chain is bad...

 

thats what many of us here in vancouver/ a few washington and vancouver island ppl thought too but i don't think the dealer is willing to consider that as an option because it means a lot more work ahha

 

no my engine is complete stock, i have not modded my car in anyway, so i dont know y this is happening?

 

mine did the same when I was stock, and now it sounds the same with the stage 2.

 

so did the sound stop or just start again with stage two?

 

im going in for the same thing again 2morrow morning...i'll let you know what they're gonna try to replace or w/e this time

 

Indeed...
Put your ear next to the timing chain housing and see if you hear any clanging, lol.

 

It never changed. The car runs completely fine, all the way to the 7000 redline. Its not that the idle goes up and down (rpm wise), but it just has a little putter noise every so often. It happens more if either a: I have been driving the car along time b: The temp of the vehicle goes over 180f.

So ya, it hasn't changed from stock to stage 2.

 

well i took it in this morning, and the guy just called me and said that they have to replace my chain, and the tensioner, he said that the parts will be in tomorrow, I can drive the car but he wouldn't recommend it because the engine could seize up, so hopefully the part will come in tomorrow and everything and I will be able to pick it up.

 

My car has had the pufft pufft idle since day one. It does it more after being driven for awhile . It will purr along for 5 seconds and the go pufft ....purr and then go pufft again . lol this post sounds stupid, sorry.

 

Nope, not stupid. My does the exact same. Since it was brand new.

 

Same here!! thats why i thought it was normal....but i guess i should probably get that checked.

 

bumping an old one i know. Just wondering if anyone found a solution?
