Very cool Gladiator. Here's to nice days! Avoiding heatstroke! Cooler weather!
Dogvan was running rich, and annoyingly crappy er. So. !988 B250 EFI 5.2, 4 speed auto. 148K survivor conversion. Dodges little 318 workhorse engine. First year EFI in the V6, and 5.2 V8 B vans. The 5.9 was still a carb engine in 1988. This 318 has the A500 OD auto, my 94 MPFI 360 has an A518. These transmissions are geared slightly different, and are well mated to the output of each motor. Which by modern standards, is not much.
R&R O2 sensor. Plus put in a new set of plugs, copper plus nothing fancy Autolite. Plugs came out very fouled, with black carbon buildup. The O2 sensor was suspect, as per the increasingly rich running condition. TBI isn't MPFI, or TPI, but you can troubleshoot it, it's not that complicated.
Had already done cap, rotor, wires, T-stat, coolant temp sensor. Timing was way out. did all this in 2015.
Glad to report, it runs good now! Go Dogvan!
