Erratic Idle.

Same suggestion - probably the intake manifold gaskets.

What was the story with these? I recall discussion that a TSB was issued to lower the torque specs for tightening the manifold bolts due to stress on the gaskets. Anyone recall this? What were the corrected specs?

Really? First I heard about this, but it would make sense, considering I have been through 2 sets of gaskets in 2 years time because of the !@#$ing 171. I was ready to just mig weld a beautiful bead around the plenum and seal it up for good, heh.

After replacing my IAC, and PCV, then cleaning both MAF, and EGR, it ended up being my intake manifold gasket

Thank you for the input. I'll change the plenum gasket and watch the bolt torque.

I think the original torque spec was 18 and dropped to 13 cause of all the gasket failures.I changed both upper and lower and torqued to 13 and have had no probs.yet

i must say i have had an issue twice recently where i have pulled to a stop at a junction in drive and the revs have climbed and its tried to power forward into the road!!!!

My 300zx had an Idle controll valve that i cleaned up to sort the idlle out......what does the vx have??

[taylorRichie]

It has an Idle Air Control Valve... Right above the Intake hose. I cleaned mine first... didn't fix the problem, so I replaced it... didn't fix the problem

HA...

Those $3,000 Scantool deals the dealership has can come in handy... wished I had paid the $50 diagnostic fee before pouring good money after bad...
