High rpm?

[Dave88]

i've had plans on replacing it, their like 60 bucks at nappa

[james750]

it should pop right off without too much trouble...

[Dave88]

OK i unhooked the airfiler tube from the box and held my hand over the tube, to try to slow down the rpms and it went back down to idlespeed and i took my hand off and its running at idle speed. i figure it just super dirty. :roll: . I'm gonna buy a new fuel filter, some carb cleaner, and trottle boy cleaner tomorrow. I'm just happy it runs good again.

That indicates to me that you have a vac leak.

[Dave88]

:cry: explain?

start removing vac lines off your intake and plug them with your finger.. When you find the faulty one your truck will run normal..

[Dave88]

it runs normal now.

[james750]

i would think that if you blocked the air intake on a normal operating mj with no vac leaks the idle would drop way below average rpm if not cutting out completely. that indicates that air is getting into the system other than the intake via a vacuum leak.

[Dave88]

I covered it until it sounded like it was idling normally, then let go and it stayed there. if i would have kept covering it it was gonna shut off on me.

[Dave88]

Now when i start it it runs fine.

[james750]

hmmmm. have you cleaned IAC and TPS?

replacing map lowered my normal idle a bit too.

[Dave88]

if you call cleaning spraying with pb sure. tomorrows job will be clean everything. Only problem i had so far is a can't get the intake hose off. those three screws are like welded on there. i sprayed them with pb 3 days in a row now and i just broke the only bit i had for my ratchet now all i have is a star screwdriver. :cry:
