Hello everyone am new to the forum and just bought an 88 convertible. This is my second 7, had an 88 SE back in 89. The guy I bought it from changed the secondary injectors out to a pair from a GSL-SE. Looking at his work all he did was cut the connectors from the GSL-SE and plug the wires into the original cannon plug on the harness, I dont see any of the 10 ohm resistors that everything I read says you need. I was getting some hesitation at 3800 but I reseated his wires ( one looked loose) and its not doing it anymore.
So what symptoms or impacts should I being seeing from the impedance mismatch?

 

Put the stock injectors back. You are running way rich, which is part of the cause for the hesitation. No reason to upgrade injectos without radical (big bridge or peripheral) porting.

The other half of the hesitation has various causes. Search "3800 rpm hesitation" for info.
