98 Maxima won't start after replacing rear valve cover gasket
After replacing the rear valve cover gasket the Maxima wont start properly. It cranks then the idle jumps up and down and then the car dies. any ideas? my though is something with the throttle body since I removed it from the intake.

Did you replace the upper intake manifold gasket, or are you re using the old one.
Suspect a vacuum leak of some kind.
the uim gasket is first on the list. Perhaps a hose clamp isnt tight enough.
The throttle body might need tightening.
did you replace the gasket between the uim door handle tube and the uim.

Sorry for hi-jack the thread. I currently have intake manifold off and my rebuilt injectors are in mail. So before I am putting everything together. Just curious that how many of you have reused the old UIM gasket without any problem?

Consider the pita involved if you need to replace it a second time. What is your time and back ache worth to you. Do you feel lucky?

Most people disconnect the cam positioning sensor to give a little more slack just double sure everything plugged in try that first.

Never worth the risk of using used gaskets.. if you went through the trouble of taking it all apart, save yourself the peace of mind and get new gaskets. As mentioned above, double check you plugged everything back in.

Yeah thats what I was going to suggest was look at the egr tube gasket. Although you should replace the UIM gasket sometines you can get away with it if its in a good enough shape and it shouldnt cause starting problems at all.
