OK here we go.... 85 22RE 30K since rebuild in 03. It starts fine and idles fine for about 10 minutes then just stalls without warning. Starts back fine but sputters and blows blue smoke around 2K RPM then wants to stall. Drives great under hard acceleration but then sputters when using the gears to slow down. Here is what I have done so far: New fuel pump and filter, new air filter, new PCV, cleaned dash pot, new plugs and wires, seafoam in the gas tank, checked every vacum hose i can find and cant find a leak. Again it runs fine for the first 10-15 minutes but after a few heat cycles it gets sick? any ideas are much appreciated! Thanks

Im just throwing out an idea, but check your coil, sometimes a bad coil will work until it heats up and then start acting up after it gets hot, also pull the vacuum line off of the fuel presure regulator and make sure there is no fuel in the vacuum line, if there is the regulator is bad.

 

Nice.... Sounds like it could be a winner and I will try it when i get off in the AM. Question: Is there a way to check the coil with out just buying a new one? and where is the fuel pressure regulator vaccum line? Thanks a ton!

 

Is it right under the throttle with the dash pot filter hanging from the bottom?

 

I really don`t know how to test a coil, but there not that expensive. I replaced the coil on my 86 4Runner because it had over 200.000 miles on it and i figure it was just a matter of time before it went bad. The fuel presure regulator is on the back of the fuel rail, by the EGR valve.

 

Yeah I looked coils up and they are under $40. Ill pick one up and give it a shot and check the old fuel pressure regulator. Thanks again

 

does ur re have a egr valve? could be that maybe could be the seafoam that u put in too idk bout it at all really but i havent heard much of anything good bout it. did it do it before hte seafoam?

 

I do not know if i have an EGR valve. I never looked. It did do it before seafoam. Ive put that stuff in all my cars / trucks once a year for 2 years with good results

 

Look down between the back of the upper intake and fire wall and you will see the fuel presure regulator screwed into the fuel rail.

 

OK fuel presure regulator is good. Put a new coil on, cleaned the EGR modulator, and blew air through the EGR valve. Got better for about 20 minutes and then acted up again. Im thinking it has to be the EGR valve due to the fact that it is fine until it gets good and warmed up.....so Im gonna replace it this week. Good news is the new coil made it start and idle way better. Lets just hope a new EGR fixes the big problem! thanks again
