Tacoma Shutting off

Hey guys Im still new to the forums and dont know much about tacomas, anyway this is whats going on...

If I floor it on the freeway, or sometimes even if I just rev it really high in Neutral or Park the engine will drop RPM's after I let off of the gas pedal, and then the rpms drop and the engine turns off...Upon trying to restart the car, it wont turn over unless I give it a little gas at the same time...and then after it starts up as soon as let my foot off of the gas it just drops rpm's and turns off again

eventually I can start my car up normally and drive normally, but it has happened a few times when I floor it like that.

( I know the obvious answer is just dont floor it like that, but I want to know what the actual problem is so I can fix it)

thanks in advace...any suggestions are welcome, I have no idea where to start

 

Clean your throttle body butterfly valve!

 

That happened to me the first time I put that 10% ethanol gas in my truck. I was on a long haul road trip so I couldn't pull the tb apart but I did put about 2 bottles of fuel injector cleaner in it and it solved the problem right there. Hope that helps.

 

thanks guys, it looks like ill be getting a few bottles of fuel injector cleaner, and some throttle body spray!

hope this works otherwise it looks like it might start getting expensive :/

 

if that doesnt work, i had the same issues and it turned out to be a dirty MAF sensor...

if that still doesn't work, it could be your Idle Air Control Valve... if so, THAT gets expensive to replace as i believe it's a dealer only item...

 

While your cleaning the throttle body clean your idle air control valve also. Should help.

 

yah, what Josh said... clean it first...

 

X2 about the MAF. And buy some SeaFoam Deep Creep spray. Use that to clean your throttle body. Works wonders.

 

Check your vac lines, and rubber intake parts for cracks...feel around and listen.

 

My 99 is doing that. What did you find that fixed it?
