How TO Replace the Intake O rings?
I am going to buy the parts and do it myself, but want to know before I take it apart just exactly which parts I gotta order. Does anyone here know from experience which gaskets I'll be needing besides the O-rings? It's a 1998 4.0 SOHC V-6 engine. It's got 125K miles and never had the intake seals changed. It idles too low especially when cold. It gets about 17 mpg on the highway. I have replaced the IAC, Inlet air temp sensor, TPS, egr, pcv, air filter, fuel filter, spark plugs, wires, and probably a few other things I cant remember. NONE of the above items changed the idle problem at all. I can hear a very loud hissing all the time which i blame on the plastic intake, but maybe its a leak. I have tried spraying all around the base of the intake, but the idle never changes. Maybe I should try that when it's cold.
So if anyone can please suggest what parts I need to get with the gaskets, and what the torques are for everything, that would be awesome. The local parts stores never have the book for this POS exploder.
Thanks guys
