When I start my truck up when its cold it likes to blow out black smoke. Also for about 20 minutes after running it. It likes to just about die when I let off the gas and then give it gas again. That really sucks when you try to cross intersections hoping your truck wont die. And I just put a new MAF sensor in. Thanks for any help in advance

 

its running SUPER rich. TPS perhaps?

 

What is a TPS

 

that does sound like its running really rich. hows your gas milage? to be blowing black smoke i would expect your milage to go down a bit.

 

yes it sees down but cant tell for exactly cuz I have bigger tires than stock

 

TPS=Throttle Position Sensor.

 

Could be a lot of things,check the codes.Pull the vacuum line off the fuel pressure regulator,any fuel there?

 

i checked those lines ant they were dry. But the last time I ran the truck was last night.

 

just leave it and tell everyone u swaped a diesel 3.0 in

 

LOL thats a good idea.

 

Did you figure this out?
My buddy's 4runner is doing the same thing.

 

no i haven't but I just picked up another 3.0 to replace it. Me and my buddys drained the oil and there were big chunks of metal and coolant so my problems run way deep. So hopefully This will fix the problem by getting a new one

 

gotta love that solution..
