  1. Most of the time a backfire in the intake manifold/carb. is usually a lean condition or the ignition module and stator are shutting off and back on due to heat transfer thru the distributor. Running out of power while under load (climbing) sounds like you do not have enough fuel flow to the carb., in other words the fuel pump cannot supply enough fuel to the carb to keep the float bowl full. Those two areas should be your primary concerns. If your mechanic can't check that correctly, I would be looking for another shop. Just my opinion. I have been in the automotive, marine, RV and race engine business for over 50 years. You can PM me here and i will talk you thru this issue.
  2. Just a few questions. Did you have the fuel pressure checked. When you say internal fuel pump was replaced, do you mean there is a pump in the tank or are you taking about the accelerator pump in the carb. If the carb was sitting for a long time and not ran the accel. pump will dry out and cause hesitations. if the accel. pump is not suppling enough fuel into the venturies, it will backfire back thru the carb. Does it backfire in the exhaust? If I am not mistaken it has an ignition module and pick up coil (stator) in the distributor that can cause this issue if backfire is in the carb. Did your mechanic check to see how many degrees of slop is in the timing chain? Just a a few things to know before trying to help diagnose your problem. If the fuel pump is in the tank you would probably are talking about the throttle body. It kind of looks like a carb., but has two fuel injectors on top. you can PM me and ill give you my phone number and i can walk you thru what you need to check.
  3. I had to relog in to get everything to work again

    Praying that all goes well, Herman
  5. Because it's a CAT, you would be doing yourself a favor and have an expert/professional do the diagnostics
  6. I have installed a few Diablo's on a few customers rigs. My suggestion is don't waste your money. Your hp and torque gain is minimal at best. If you do decide to try a programmer, DON'T put it on the performance setting unless you have deep pockets. Make sure you install a EGT gauge before you do anything. Just my opinion.
  7. You need to replace the valves with new valves for health issues
  8. I agree with akadeadeye and docj. national needs to listen to the membership and climb out of the snafu box.
  9. Sure. It's worth a try. Interesting idea
  10. It was done with the block (cylinder head deck). it only raised to compression but it also raised the torque significantly.
  11. The 440P engine used different rods to handle the compression increase. Be careful when adding stuff to increase performance.
  12. Yes. I have a set on my 04 Holiday rambler 38'. I had my coach weighed and run 98 pounds in the front and 90 pounds in the rear. Have had them for 2 years and have had no problems. Hercules does not build a rv tire in that size. Mine are OTR and no abnormal tire wear. They are very quite and the wander i had with the Hancooks is gone.
  13. We are planning for that rally now. Looks me up if you can make it. Would be nice to put a face with a name.
  14. The Western Area Rally held in January has been cancelled. The Feds are still using the Indio Fairgrounds and will not be releasing it until December 31st at the earliest. We were really disappointed but had no choice. Rick Ammerman F442485 WAFMCA Vice President Central
  15. If the a/c vents work normally under normal driving conditions, the leak could be anywhere. I would start looking for the vac reservoir and testing the vac signal in and out. I have had many reservoir tanks crack (plastic). just a thought
  16. I had a customer once about 20 years ago that installed a CB radio in his class C and really did an awesome job. The only problem he made was he secured (zip-tied) the antenna coax to the ECU harness. Every time someone keyed up, the engine would shut down. I moved the coax about 6" away from the harness and everything worked just fine. Be careful.
  17. I had one at the shop that was doing the same thing. It turned out to be a defective ignition switch. The switch connector became loose and melted the power wire. sometimes it would work after it sat for awhile, but as soon as the current flow heated the connector back up it would loose connection again. It's easy to see the back of the switch with a flashlight and mirror. Just a thought
  18. I received a new pump unit late last night. Installed it today after work and everything is functioning correctly now. Now I get to disassemble the old unit a see if I can figure out what happened. I’ll let y’all know after while. Thanks for your help!
  19. Are your batteries sealed or do they have caps? If the have caps you can check if one or both have a dead cell. You can also take the batteries to O'Riellys and they will test them for free. One dead cell will drain a fully charged battery over night.
  20. Back in the day, Chrysler had an issue with the ignition module and the pick up coil (stator) in the dist. When i had a vehicle in the shop with an intermittent engine shut off, we replaced both components and the problem was fixed. Both components are susceptible to heat from the engine compartment (module) and engine block temp for the stator (pick up coil).The module is easy to change, but the ststor is a little more difficult. You can PM me and i can walk you thru it.
  21. Thank you. I hope all is well with you and yours
  22. I was told by Direct TV that our signal was based off our zip code. When we travel too far away from our zip (300 miles, i think), we loose our local stations except ABC CBS NBC. The only thing they would do was change the zip code to where we were. We would have to do this every 300 miles. I just gave up.
