Hey Guys,
I've got a couple of questions regarding my 87 FJ 60 (stock drivetrain, smog, 203K mi). When climbing long/short, relatively steep paved/unpaved inclines the motor begins to stumble. The stumble does not start immediatley, but after plenty of throttle has been applied in the correct gear on the climb. It's a jerky on then off, on then off stumble that feels like a fuel shortage issue?? At first I thought it was linked to a faulty clutch, but after replacing it the problem still persists. I remeber some similar posts on this issue but was unable to locate them (sorry if I'm asking old ??'s). All of the emmisions eqpt. is in place, but I have a leaky PS pump :'(.
I'm leaning toward replacing the fuel pump and fliter. Is the a tough undertaking? I'm also leaning toward taking the Cruiser to a very trust worthy independent Toyota wrencher to let him sink his teeth into this problem. What do you all think?? carb, vaccum leak, smog pump, fuel pump/fltr, ignition sys.???
My hands are pretty much tied on this one, as the emmisions stuff gets a little deep for me. Any advice or comments is greatly appreciated.
Thanks
