Low idle then cuts out

[lonewolf98765]

I've had my 4runner for about 10 months now and I've done a lot to it. I did a general tuneup in the winter and after that the engine started freaking out, it used to idle kind of high but then would drop down, no0w it idles at about 1,000 rpms, and it has a slight miss (any suggestions on that?) anyways you can hear it in the exhaust. So, I did the plugs, rotor cap or arm?, distributor cap, plug wires, air filter and now it dies after it warms up! Does anybody have suggestions as to what I should do about this?

does the truck die after you shut it off and then turn it on again a little bit later?

It does, it always runs for a few minutes solid and now it just dies could it be a fuel pressure regulator??

It sounds like you have done the right stuff to it assuming you did everything right(I am sure you did, its hard to screw up the easy stuff), maybe instead of just replacing stuff now and guessing try pressure testing the fuel system at the rails. Also maybe check for vacuum leaks.

Maybe its getting too much/too little fuel when fully warmed, that's why I am leaning towards pressure testing first before you replace things that aren't broken

Hopes this helps

i have the same issue... at the moment i just deal with it... but 4bee is right, once you check out everything and its within spec, try cleaning your EGR tube in the manifold... i've read here that it gets all gunked up and nasty. thats what i'm going to do... plus a little sea foam never hurt. i'm no expert by any means and the other members are more experienced than I... good luck!

ps. when i start my truck and i feel it about to die, i remedy the situation by lightly pressing the break and gas at the same time to keep the rpm's up and get moving. once i'm moving its good. you could do that in the mean time...
