  1. Too technical for me........the terminology is over my head....
  2. I have Nick's REM and the factory DRB tool. Kinda prefer Nick's.......
  3. Intake manifold bolts can be loose enough to allow a vacuum leak. Always a good idea to put a tool on them at least once in a 4.0's lifetime. We did that as part of the 30.000 mile tune-up it was so common. Carb cleaner is a great tool in finding vacuum leaks as stated previously. If vacuum is verified all good, the MAP sensor could be faulty.
  4. I'm gonna bet the hose from the throttle body to MAP sensor is compromised. CRUISER'S MOSTLY RENIX TIPS THROTTLE BODY TO MAP SENSOR HOSE FIX JANUARY 23, 2016 CRUISER54 29 COMMENTS The Renix throttle bodies have a strange and failure prone connector on the side where the MAP supply originates and then runs up to the MAP sensor located on the firewall. This hose/pipe assembly is no longer available for purchase. The real kicker here is how critical this line is in supplying the correct vacuum signal to the MAP, the most relied upon sensor for the ECU to read regarding air/fuel ratio. Any cracks, melted spots, or loose rubber connectors can cause major starting and driveability issues. There’s a simple fix though. All that’s required is a 1/8” NPT tap, a new throttle body gasket ( Napa FPG 60742 ), a vacuum fitting (Napa 05703-B102), two vacuum elbows (Napa CRB2670), and a length of new plastic piping (Napa CRB2672). Remove the throttle body and take it to the workbench. Using an oiled tap along with a driver, carefully thread the lower of the 2 holes of the throttle body where the old fitting was plugged in. Don’t go too deep. These are pipe threads. Flush the hole with carb cleaner and inspect for any left over cuttings. This is an excellent time to do a complete throttle body and IAC cleaning. See Tip 11. Take the vacuum fitting (05703-B102 ) and apply a LITTLE bit of thread sealer on the threads only. I prefer Permatex #2 but almost anything is fine. . Carefully screw the fitting in until snug. Install one of the vacuum elbows on the MAP sensor so it points toward the throttle body, and the other vacuum elbow on your new throttle body fitting so it points up to the MAP sensor. Cut a length of the new plastic tubing (approximately 13 inches) to fit between the vacuum elbows and install it making sure there is enough slack for some engine movement. Route it according to the photo. We don’t want any rubbing or chafing with engine movement. Not a bad idea to use some contact cement or Gasga-Cinch sparingly on the tubing to elbow connectors.
  5. No problem Just making sure the pic wasn't floating around in cyber-space.
  6. They're bright as hell with the LED bulbs supplied. Just do it.
  7. Have you ever gone to my website and just scanned the list of write-ups? Might save you some time.
