Howell throttle body or Webber??

Ok all I have an 86 CJ7 with a complete Borla cat-back system I am currently running the Howell throttle body system I have 120,000+ miles on the engine and the TB has ony been on for 4/5 k miles. It runs like crap!! The system is installed correctly. I have also upgraded the ignitions system. I am starting a rebuild/restore and was looking for advice/input/recommendations on my setup I am considering selling the Howell off and going with a new intake and a Weber setup. Or should I rebuild and keep the Howell I was going to send the CPU back to them and have it checked out and updated as I was going to add a mild cam any suggestions??

I can't imagine going back to a carb after having EFI. My Howell has run great for years, and it's known to be a very reliable system, so my advice is to figure out what's wrong with yours and keep it.

Or sell it to me cheap when you yank it off

I would keep the Howell system also.

It’s a pretty simple system and shouldn’t be too hard to fix.
Does it throw any codes, and/or have you checked for codes.
TBI systems are somewhat sensitive to vacuum leaks, and bad electrical connections – check for bad grounds, clean electrical connections everywhere, check for proper voltages etc, etc.

It may just be something simple.

If you have a problem with the EFI it's either operator/install error or a simple fix.

Pull your codes as shown in the troubleshooting manual first. If no codes are thrown, call them. Don't email, call. Troy should be able to get you through any issue that isn't a problem with the ECM or programming.
