Dear Experts,
I have a 99 Lexus ES300. Fuel injection. About 110K miles on it now.
Lately when I go to start it, it just sputters. Based on experience, you think that it started, and I take my hand off the key. Then the engine stalls.
So, I start it, when it is sputtering, I have to give it some gas. The RPMs go up. And then it idles ok.
It's like the old carbureted Fords I used to own.
Any ideas what is causing this symptom, and how to fix it?
Thanks a lot!
And I bet its over due on a basic tune up and has original plug wires. When is the last time you "read" and examined the plugs, I bet never.
Any codes in the computer? Do the plugs look decent? If it were me, I'd clean the IAC valve (and I'd clean the throttle body while I was in there.... the throttle body isn't your problem but if you haven't cleaned it in 110K miles it needs cleaning), and I'd go look for vacuum leaks.

That's not correct.
The symptoms outlined by the OP are classical indications of a dirty IAC valve. I had a 96 Camry that went in annually with the 'rough idle when cold' symptoms. The shop cleaned the IAC valve and sent the car back with a bill each time.
Then I replaced the IAC valve and the symptom never recurred in the few years I had the car afterword.
