My 91 LS400 has developed a stalling problem when warm. At first (last summer) it would only stall when the a/c was on. Now will do it any time it is warm, though not EVERY time it is warm. Takes about an hour for it to re-start. Mechanics say (incredibly) to bring it in when it's doing this. Translation: "Drive it in when it's not running"???!
Plugs and wires are new. Cleaned throttle recently, but problem persists. I'm thinking fuel pump, but isnt that usually the problem when the vehicle is going at high speed? This happens randomly, it seems.
found a Denso fuel pump for 154 USD--thoughts on price and quality?
thanks
will do--thanks so much
so you dont think its likely a fuel problem...
