Looking back on the thread, Mike mentioned this a few days ago “Remember Bosch stock injectors are NOT made as a set. You could have low end of 293 bar you the high end of 327 bar. This can affect idle performance. Ihigh suggest AGAINST using stock injectors. Buy+50 HP from any good injector shop and they are balanced as a set within 2% of flow rate” I still think it’s very likely both sets of your injectors have been mismatched. I learned this the hard way over the past year or so. Had your same stall issue after I ordered and installed a matched set from the same outfit that did Mikes injectors. Pulled them out, had 2 shops pop test them and they ranged from 290 to 330 bar (both shops showed same numbers on each injector). Pulled them back out, send them back and told them specifically what I wanted (310 bar-I believe they set them up at like 308 normally) they sent them back and I had them independently tested again and they were still off-not as much but by then I was mad. Keep in mind this was a “premium” set, not their normal budget injectors. I tossed those and went with the Mach 1 from Flux bc the owners are still directly involved with building their injectors and they’re perfect. For whatever reason my 2000 model is very sensitive to matched/balanced injectors and it sounds like yours is too. This shows my truck stalling after shifted intro reverse. On a slight hill, if the initial fuel input didn’t create enough force to back it up it would just drop and stall. The pics below show the idle RPMS from 2 different tuners.

This photo is of a typical 12 valve engine. No crossover tubes. Fuel line are connected directly to the injectors, so injectors can be shimmed. John

OK thank you very much for all these informations. I like to learn. Thank you. OK. Thank you very much. I like to learn. Thank you

OK. Thank you very much. The photo of the ECM connector with the 50 ways is the photo of the connector as it is on the ECM from the front, wire side, or is it the photo of the connector turned inside out? I'm talking about the first little photo on the left.

Shown below are the pinouts for the ECM. Perform continuity tests (using the ohmmeter setting) on circuits that you wish to check. Be sure there is NO POWER supplied to any circuit being tested. For example, the APPS communicates only with the ECM. You could perform continuity tests on all of the connecting wires (see bottom photo). John

For installation, 2 new holes have to be drilled. They need to align with the "channel" in the hinge. The bracket is used as a drill guide. It will fit a 3/8 drill perfect. Reuse the one long bolt in the lower hole and a shorter bolt in the upper. A piece of masking tape works good to hold the nut on an open end wrench when installing the bolts in your drilled holes.

My guess is that if you change the height of an injector on a 24 valve engine, the connection point of the crossover tube to injector will be misaligned. John
