  1. Have you done the injector swap with the 746s? It hasn’t fully solved the problem for me, but it made it more tolerable. All those errors (except the lean loop fault) have gone away naturally, which I think is due to the computer resetting. To be honest, I think I might have an issue with the IAC because unplugging it does nothing or the MAP as my truck will get the “lean loop” fault when it’s in open loop (at least I think it’s open loop. It’s on start up, which is when open loop is used) Sent from my iPhone using Tapatalk
  2. That’s interesting! I know of a 90 Cherokee in a pick n pull yard near me. I’ll pull the sensor off of it and see if that works. The only thing is that my O2 sensor hasn’t been wacky until after these injectors were swapped in. I’ll still try it though, it’s better than doing nothing. Sent from my iPhone using Tapatalk
  3. Yeah that’s next on the list. I didn’t have any of those caps but I’m planning on going to an autoparts store to get them. Edit: just got a 5/16 vacuum cap and put a fuel line hose clamp on it Sent from my iPhone using Tapatalk
  4. After driving for a couple days, I’ve got some more news. I now get the lean loop fault and rich loop fault on startup, so I guess some sensor can’t handle me running nicer injectors. On the second startup, I got an O2 voltage code, which I’m not sure about. I don’t really think the 02 sensor is bad, considering I just replaced it with the NGK model. I’m not too sure what to do about this anymore. Sent from my iPhone using Tapatalk

  6. Just finished getting all the fittings for the tank as well as cutting, welding, and painting the bracket for the tank Sent from my iPhone using Tapatalk
  7. https://www.ebay.com/itm/153133492767 That’s the tank I bought. I think I’ve worked it out now. Sent from my iPhone using Tapatalk
  8. Yeah, but that’d take my truck out of commission for a while. I don’t have the time to replace a radiator with my school and everything. Sent from my iPhone using Tapatalk
  9. What kind of hose clamps should I use?I don’t want to use the worm gears because they’re butt ugly and they’ve been letting me down recently. Sent from my iPhone using Tapatalk
  10. Thank you Pete! I’ll look into getting one. This little tank is some universal eBay one that I’ll have to fix up to make it work. Sent from my iPhone using Tapatalk
  11. Wouldn’t the tank be pressurized still? I thought that an open system would have an expansion tank that is not pressurized. Or could I plug off that valve under the cap? Sent from my iPhone using Tapatalk
  12. So, I’ve decided to finally tackle my coolant system because after 3 plastic bottles breaking, I’ve had enough. I bought an aluminum tank to replace the plastic one and it uses a radiator cap. What I want to know is, what is the pressure rating for the closed cooling system? P.S - I won’t switch to open cooling until I get a new radiator at the very least Sent from my iPhone using Tapatalk
  13. Finally back after so long! I’ve done quite a bit with this truck since I’ve last posted. I managed to find an EGR solenoid and valve as well as replaced the fuel injectors. While I was putting the rail back on, I snapped the MAP vacuum line and just managed to get through Cruiser54’s fix. After all of that, I tried the truck again and it still has a “Lean Loop Fault” code from the Engine monitor. The only other things I could think of now which can be causing it to stumble are the block coolant sensor (because apparently it helps manage fuel/air mixture I guess?) a vacuum leak of some kind, o
  14. On a side note because chances are I’m gonna be removing this trans cooler, radiator, and AC condenser in one fell swoop, what brand of radiator do you you guys recommend? Sent from my iPhone using Tapatalk
  15. Did you use the original hard lines? Because mine are so shot that they’re leaking both for the hose clamps and the disconnects. Sent from my iPhone using Tapatalk
