I have a 1986 4 runner just built the engine,was doing this before engine overhaul.Timing is right, maf is new, so are the tps,coolant sensor,computer,fuel injectors,fuel pump,& filter.The engine is bogging down under acceleration & takes a long time to start unless I spray engine starter through the maf and the engine will start up and idle and rev up like it should.The Cold start injector is working properly.It seems that it is not receiving enough fuel.Anybody with some info is welcome.Please email me at bwc13@cox.net
Thank you Brad :banghead:

I would check your vacuum lines next.

Fuel pressure is correct?

went back after banging my head on concrete,it was the regulater.the thing was bent but i didn't see it before i put the engine back in.Thanks for all the info. :smokin: :biggrin: :lol2:
