01 Jeep Cherokee injectors

Which injectors should I get with a modified engine with free flowing exhaust and a 62mm throttle body? I have tried the bosch upgrade but I had trouble starting the jeep with these installed. I had to hold the pedal to the floor to start. It seemed to run rich when started. I could smell fuel from the exhaust. It has a bigger cam and ported 0331 head.

Did you reset the ECU after installing the bosch injectors and drive it for a few days to let the system re-learn? If it already smells rich I don't think you need bigger injectors.

It's possible one or more of them is stuck open as well, if they weren't cleaned up/tested.

The factory injectors are well capable of meeting the demands of a factory ECU.

Digger87xj has it right.

I have a 90 with a Borla exhaust system from the head to the tail. In additon, I have installed the adjustable MAP circuitry.

When my stock injectors started leaking, they were replaced with equivalent ones from an aftermarket injector supplier. They were Bosch injectors. What is critical is knowing which ones you should have. They do vary over the years with respect to fuel pressure changes.

The Bosch injectors with the 4 holes seemed to run rich. Yes I resetted the computer. I ran these for one week with no change.
