Re: [SPOC] timing chain

[Ryan Jenkins]

The timin chain will make lots of rattling noise before it goes bad... you'll hear it... and then you replace the chain, tensioner, and guides.   As for high idle, take off the TB and clean it thoroughly (remove the TPS and IAC sensors) with carb+choke cleaner or brake cleaner, and re-install and re-set the idle control screw so it doesnt idle so high (maybe around 900)   Ryan ----- Original Message ----- From: Alan Lu To: spoc Sent: Wednesday, April 10, 2002 7:48 PM Subject: [SPOC] timing chain I have a 93SC2 with 122K miles on it. how do I know if I need to service/replace my timing chain.
