IAC ? how do u clean

how do you clean the EGR valve(if possible)
and what is the IAC?
my car only dies when its hot,:banghead: and my oil pressure gauge max's out at 2000rpm's when cold
when warm its fine,but my oil light flickers,and my rpm's bounce between 1000 and 0 then dies:banghead: unless you keep rpms at 1000 or higher.brakes are expensive lol:banghead: im going frickin crazy here:runaround:
please help me
thanx guys, u all are very helpfull

There is a piece of carbon stuck holding the pintle valve open and this is a common problem.You have to hold the pintle valve open getting that piece of carbon out.You can get an EGR valve gasket with a filter in it at most parts stores and is not cheap.Carquest does sell this gasket.The IAC is Idle Air Control and you can clean it with Carb cleaner

What yr. & engine?
Thats a good way to go about buying another IAC valve. Use nylon scratch pad with diesel & thinner mix to clean. Only apply to cone of valve as any cleaner getting into solenoid area will cause decomp and freeze pintle in one position, causing worse problems. If you check the manual it will tell you this also.

You might wanna replace the oil pressure sensor...you may be getting low pressure fuel cut off from a faulty reading...sounds like the reading is too low, and as the oil warms and thins it gets even lower, so it will cut it off at idle when pressure is lowest, if it falls below a set value (I forget, 10 psi or something?)

If the reading is correct the oil pump could be worn out or the screen is blocked...

If you run 5W30 and the engine has plenty of miles you might wanna move up to 10W30 also...

This may not be the right answer for you, but, I had problems with mine stalling at redlights and would idle eratically. What I did was drain a pint of tranny fluid out and put a pint of seafoam trans tune in. this will lubricate the tcc enough where it wont stick. also, I changed my trottle positioning sensor and Idle air control. $40 each. after running around a few days with the trans tune in, I flushed the tranny. Havent had the stalling or idle issues since. make sure you triple check the amount of tranny fluid you/they put in. running too much will make the car surge and lose power. if this doesnt cure the prob, definately check to see if you cat is backed up. one step at a time, you'll get there.
