leftfooter Posted July 9, 2010 Share Posted July 9, 2010 I've been having spluttering problems w/ low idle recently & after reading on here I've decided that the Throttle Body is going to get a good cleaning. While I'm @ it, what else should I replace to give the car a good service? I have a mechanically minded friend who is going to help me, need to know what to buy.... Here are some suggestions, please add or remove if you think it's appropriate... Clean the throttle body plugs, wires, caps, and rotors Fuel Filter seafoam or Meet oil and air filter, added fuel cleaner and an octane booster 92 LS 400, 163K Quote Link to comment Share on other sites More sharing options...

RDM Posted July 11, 2010 Share Posted July 11, 2010 Yes. All automatic transmissions have a filter. Some are not serviced without removal of the transmission, but the LS is not one of them. There's a pan and drain plug just like the oil. Filter is behind the pan. Quote Link to comment Share on other sites More sharing options...
landar Posted July 11, 2010 Share Posted July 11, 2010 Service also calls for coolant change, brake fluid flush, differential fluid change and cabin filter. Save your money on the fuel cleaner and octane booster. It is not needed. Just use premium gas. When was the timing belt last changed?

yank30265 Posted July 18, 2010 Share Posted July 18, 2010 while cleaning the throttle body i also found my egr valve ports caked with carbon; clean that out and the filter in the egr modulator Quote Link to comment Share on other sites More sharing options...
