1978 Jeep CJ5, fiberglass body, 1990 Ford 5.0 EFI engine. I've been chasing a TFI killer for 10 years. It hasn't been a constant. Frustration leads to the vehicle (Jeep) being pushed into the garage and ignored. In the spring I get excited, find a new solution or a mechanic to "fix" it and I'm...

I have a '90s 5.0 swapped in my Jeep. It ran great for a very long time. But the last 6-8 years it's been eating ignition modules like candy. Seriously, the latest one lasted about 6 hours of run time. I've spent so much time and effort chasing this issue that I am just DONE. I'm tired of...

I'm fighting some demons in my 1978 Jeep CJ5. I'm reworking the 5.0 fuel injected engine wiring. The wiring harness instructions require a wire that is only hot during cranking to "kickstart" the ECM. It says that it shouldn't be hot all the time as it will cause a rev limiter condition. Since...

I've been chasing some gremlins trying to find the thing that's killing my ignition modules at a rapid rate. I didn't want to add to my previous post as I found an answer of sorts. Over the last year I did an engine swap in my Jeep CJ5. The 5.0 engine and the EFI system are from a 1990 Crown...

I'm chasing whatever is killing my TFI modules. I'm dealing with a 5.0 swapped into a Jeep. After driving the Jeep for a while the throttle starts to be lazy. It seems to get progressively worse. The engine will start stalling when the accelerator is pushed. Eventually dying on the side of the...

I'm currently running a EFI 5.0 from a '90 Crown Vic in my Jeep. It ran without issues for over 10 years. Then two years ago in the middle of summer, the TFI literally broke in half on the trails. I swapped out the broken Motorcraft module for an AutoZone module, and that lasted for a year or...

81-83 2.3/T5 bellhousing question I have a 2.3 EFI swapped into a Suzuki Samurai. I'm running a modified pinto four speed. I'm currently re-doing the swap and want to upgrade to a T5 for the OD. The bellhousing I have for the T5 has an arm/pivot on the outside of the bellhousing. I really don't...
