Rough Idle ! ? ! Tune up time ? ? ? . . .


Recommended Posts

Ok normally i fire the ol'2.5er up let it run through the High idle cycle then drive worked great all last winter and throught till about a week ago . . .

 

It now has some hesitation while acceleration like a half miss type sensation, Once heated up hot goes away runs great but idles a bit rough and has progressively gotten rougher . . .

 

Sensor's have all been replaced, Vacuum leaks have been fixed, and i even fixed that exhaust leak so i'm guessing its timing chain ? or tune up time ? . . .

Once it reaches operating temp for a few miles it'll chitty chatter while idling . . . Sound's like a loose timing chain rattle against some thing or Rust on the Idler pulley but that would wear off and be here cold as well as hot . . .

 

Maybe the old 2.5er is wearing out :hmm: there is 195K miles on it after all :yes:

 

Unless its just supposed to chatter, I know GM's 2.5 rattled and CryCo's 2.5 chattered, just this sounds way different then the racket those 2 engines make . . . But then again this a different 2.5 . . .

I guess different 2.5 means different Rattle/Chatter Seems like all the Big 4's from the home land make noise of some kind even them Ford 2.3s Clattered once they got miles on them.

 

I would still like to know whats up with that rough Idle and if the Chatter/rattle/Clatter is part of it ? been noisy since i bought it, the rough idle is a new thing . . .
