Please help! I have a 1995 4runner that I have put THOUSANDS of needless dollars into, just trying to get it to run right, and if I didn't need it to get to work every day, I would have burned it to the ground by now.
Soooo...here it goes. Got the truck for $700 after sitting for a year plus. Second rebuilt motor I put in (first was defective, but under warranty, so I only had to pay for the installation labor and $800 shipping. lol) never ran right. Rough running, weak power. A couple years, and a few thousand dollars later, I've replaced the fuel pump, fuel filters, O2 sensor, knock sensor, plugs, wires, TPS, ECM, every iar and vacuum hose replaced and a few more parts I can't remember.
Latest issue with it is that it won't start back up after warming up, or it bogs down after sitting idling for a while. So, a typical scenario is this: In the morning it may start right up. Usually. Sometimes when it's cold, but almost always hot, it will seem to start fine, and then sputter unless I hold the pedal down 3/4 to full, and rev the shit out of it, and I can hear it kinda clear out, and then it will run fine until I turn it off. At say a drive-through and I'm sitting, either it will go into safe mode and code out, or when I rev, it sputters for a good 20-30 seconds, clears out, and it will drive fine.
Added some gas in the air intake to see if it's not getting fuel. It started up fine and then quickly died like it's getting no gas. Still, checking the bleeder valve shows that there's gas in there. So, it seems heat/fuel/air/spark related. That's pretty much the whole truck...
But I'm narrowing it down to AFM or the coolant temp sensor, or something. The AFM is $200, and I can do that myself. The sensors are all behind the plenum, so I'd probably need a pro for that. Any suggestions before I go blow $200-$500 trying to replace enough junk to fix it?
