I have just purchased this vehicle for my daughter so I do not know about status of LIM and UIM gaskets......while I'm replacing plenum I plan to go ahead and put in the metal gaskets while I'm at it...... THEN, it dawned on me while out today that in an effort to get this engine running again, I sprayed Starter Fluid into the intake to see if it'd just run a second or two.... THEN when I put another module on it today....I guess with the correct spark, it ignited the fluid I spayed in the intake that was sitting in there....... my bad...... lesson learned.
