just deleted the mess under the intake and still have a bad idle....

[Mike The Bavarian]

well rev...As i was working on my car today(timing chain tensioner and new expansion tank bleeder valve) I notice....you guys were right...Huuge hole in my intake boot. It wasn't there before. thing's so brittle it must've ripped when i put it back on. thank god it wasn't the icv. I cleaned it anyways but I'm gonna get a new boot and I'll be good..

[Mike The Bavarian]

Nope. I'm waiting to get paid. so i can order a few things i need.

[iamsam]

wooaahhh buddy. I figured that from the begining. I was just seeing other peoples thoughts on it. I needa replace these parts anyways.

did you get another one yet? just helping you out, buddy.

[greanthumb]

still haven't bought it. My car's not on the road so it's not that big of a deal. But i still wanna fix it. I'm getting a intake boot and timing chain tensioner this week. and a new radiator bleed valve....mine's cracked.

if you want to get a new intake boot. carquest carries one pretty cheap. like 25 bucks or so. i had to replace both of mine

[Mike The Bavarian]

its your freaking ICV. Find one at a junkyard. I spent $8 on a junkyard ICV for my M42 after doing EVERYTHING else to fix the idle, and bam, back to perfect.

did changing the intake boot do the trick?

not being rude, but are you relatively new to the m42 ?
chain noise is often the tensioner, but can also be low oil pressure ( bad thing)
on eof the problems wiht the m42 is that the oil pick up bolts get loose, and some oof the other bolts in there, and then the pickup starts sucking air too,

this is an easy fix, easier then what you have already done to the car

so if your ordering all those parts, get the lower oil pan gasket, drop it, find the pile of bolts in the bottom, clean things up, reinstall with loctite
my car had 3 bolts laying in the bottom, others have had more

there is also a write up on " the easy way" to change the tensioner

Not really. I know my way around the m42 and it's problems pretty well.

i have a weird idle also but i know its my o2 sensor and leaks

[KenC]

yeah. My intake boot is cracked, but it's been cracked since i had the car and it never used to do this unless one of the lines came disconected. I'm going to get a new boot and check my fuel pump. I need to do my chain tensioner too.

Replace your intake boot... should solve the prob. If not, might be your ICV.

[JoeyBones]

that is good and all, but make sure that if there are bolts in the lower pan that you check the gasket on the upper...if it's been hanging/leaking then the gasket there could be shot. In which case you're in for a world of fun...

back to the idle...I haven't done the mess thing yet, but it's on my list. My biggest issue is that after it runs for a while, if it dies, it will not idle from that point on until it sits...dunno what that is, but if i had to guess it's gonna be fuel filter, or bad ICV

the icv can be serviced to a point, you can take it off, spray the crap out of the internals with carb cleaner ( or the like) and free it up, sometimes they get sticky. a loose connection will too.
look at the fuel pimp, well "looking" wont help, checking with a meter will.
how about the fuel filter


removing the fuel rail, and bumping an injector can cause an old dry seal to finally give up

also another spot ( from experience) is the big "boot" going from the afm to the intake gets brittle with age, and removing and handling can put a crack in an old one, thus causing your symptoms too

so like has been advisied, carb cleaner/starting fluid sprayed around will find intake leaks

otherwise its the muffler bearings
