shelbyone Posted August 26, 2021 Share Posted August 26, 2021 great..exchanged Fuel Pressure Regulator, 2% flow matched Bosch II Injectors, new Platinum Spark Plugs, new MAP, new Rotor&Cap, new Spark Plug Wires, new Fuel Pump&Filter...and now: code 26, three times in a row! and code 24 26=injector current limit not achieved 24=throttle positioning sensor circuit I mean...what the actual F$%# any clues?

Hemi Dude Posted August 27, 2021 Share Posted August 27, 2021 Wrong injectors. Have you fussed with the TPS. Link to comment Share on other sites More sharing options...
shelbyone Posted August 27, 2021 Author Share Posted August 27, 2021 (edited) wrong injectors? how is that possible? before I changed out everything, there were zero codes... Edited August 27, 2021 by shelbyone typo (see edit history) Link to comment Share on other sites More sharing options...

( they all seem to work fine...) except for the constant check engine light...and the codes...great...I am NOT amused...

Hemi Dude Posted August 27, 2021 Share Posted August 27, 2021 Well, this may sound silly, but I also have a '85 Plymouth Voyager that came with a 2.6L MMC engine. The camshaft had snapped, leaving cyl. #4 inoperable and worst of all, the water pump as well. Long story short; I installed a 3.0L with 87 to 89 specs and a SMEC to accommodate it. Years later I acquired a 3.0L from a '91 TC that I first rebuilt and installed in the van. I also ended up with that same 'injector current limit not achieved'. It turned out that I had to install the injectors from the old engine to make the SMEC happy. Check the impedance on the old and new injectors and see if they are the same or very likely different. You'll know what to do from there if they don't match. 1 Link to comment Share on other sites More sharing options...
Reaper1 Posted August 30, 2021 Share Posted August 30, 2021 I agree, I bet you need high impedance and you have low impedance. Worst that will happen is eventually fry the injector transistor. Not exactly a good thing, nor very repairable by average DIY folks without replacing the entire SBEC (his is a '91, so, should be SBEC, but still batch fire because it probably is using '90 electronics). 1 Link to comment Share on other sites More sharing options...
shelbyone Posted August 30, 2021 Author Share Posted August 30, 2021 just receive a reply form the company who send me the 2% flow matched injectors: "All of the online catalogs that we are referencing have the blue top Bosch injectors listed as the stock for your vehicle, but since the ones you pulled out of your specific vehicle are different we will want to make sure we get you those same ones" I am curious why these, altough stock, give me these errors...

Reaper1 Posted August 30, 2021 Share Posted August 30, 2021 Have you measured the resistance of the coil on the aftermarket one versus the original one? They should be very close. 1 Link to comment Share on other sites More sharing options...
