Name that injector.

pn. 4418335
Wondering what the flow rate is on these? I checked Gary's site and all I could find is "unknown on '89-93 fuel rail, not a good part number".
These were on my '88 Daytona Pacifica (2.2-T1) but I found a recipt in the glove box where a PO had a shop change the engine, so who knows where any of the parts came from...

I changed them out in favor of a set of known good 4418258 injectors ('89 T2 33 lbs/hr) while trying to find the source of a miss at idle. I'm just curious to know if there is any difference in flow rate between the 2 sets of injectors.

Also, while I'm on the subject, I pulled the injectors out of the '89 2.5 I got from a local salvage yard and they had no part #'s what so ever. Wierd!
Thanks,
Tony

Yes there is a difference. The 4418335 injectors are the 27lb/hr injectors. There should be an H on them.

Thanks Frank! So, the 33 pph injectors should be a slight upgrade then? The computer doesn't seem to have any problem with them. The A/F guage is bouncing like normal at idle and part throttle and holding 9-10 leds (10 led guage) under boost.
Thanks again,
Tony
