I recently purchased a 78’ FJ40 with a Holley Sniper EFI kit and brought the truck from flat New Orleans at 0’ elevation to hilly East TN and 1000’-1500’ elevation.
I love the Sniper (it is a Mosley kit with the inline fuel pump installed by 49 Tire approximately 2000 miles ago) and everything seems to be operating as it should, quick starts after prime, strong throttle response with the exception of climbing decent grades in 3rd gear at about 2200 RPM. At that point it seems to hit a flat spot and slight sputter and the afr dips to yellow 9 or 10 from 13 or 14 and stops making additional power, it also goes into learning mode.
Is there a different setting or other corrective measure needed or is this a somewhat normal adjustment to change in elevation and hilly terrain and will improve with additional time at elevation?
