Idle probs FIXED!!

Did you check for OBDII codes? Are you running a stock OEM air filter? If not try it, it gets you back to 750.

When I had the issue, it was throwing no codes whatsoever. Suprising yes, but only consider OBDII was mandated by the govt in '98 year vehicles or later. OBDII was kinda in its infancy in all our VX's. It has matured since then to include much more information.

Thanks for the detail feedback and itemization (or process of elimination for that matter) as mine is doing the intermitt. high idle deal as well and for $90.00 and some time, it sounds like a no brainer. Once again, thanks for your time and effort!!

So far so good, I replaced idle control valve, instead of just cleaning like normal, and no change, than replaced throttle position sensor, which I have never done, and big difference, not sure it was ever that smooth of an idle......right at about 800 idleing..so perfect. And no codes here either or it would be tons easier......fingers crossed!

I did the throttle position sensor and idle control valve with Autozone parts (Duralast - 2 year warranty) and my idle is fixed!! I also cleaned the throttle body and threw another PCV valve as well. SO far SO good!! Parts were $76.42 OTD from Autozone in Mira Mesa, CA (suburb of San Diego County).

PCV Valve: Luber-Finer PCV1193 $3.29
Idle Valve: Duralast AC143 $44.99
TPS: Duralast TPS121 $21.99

I had a problem with stalling randomly and running hot. It was driving me nuts. I don't have a check engine light (PO killed it I assume).
I had replaced the fuel pressure regulator and fuel filter but still no change. I finally borrowed my brother's scan tool and found a couple o2 sensors reading lean and a MAF code, along with an EGR code. I cleaned the MAF with spray cleaner and that seems to have straightened out the issues regarding running hot and stalling. I'm not concerned with the EGR. Man was I glad to have her back to normal...

The hot weather has made my stalling gremlin return. sometimes stalling several times a trip.

I tried the fuel pressure regulator first. Big mistake. you have to be a glutton for punishment for that one. Not only did I drop the custom made allen, I made a lanyard out of electrical tape so I wouldn't drop it again. I had to shave a little off each face of the metric allen to get it to fit the bolt head.
Anyway after test driving for awhile about 20 minutes later it stalled a few more times.

I replaced the throttle position sensor next!
So far it has not stalled, but the car didn't like responding to the throttle the first few miles. but 20 minutes and yet to stall. Since it has cooled down for the night, I will have to report later to say if this is the one.
So far, I'm thinking it is.
It wasn't...
