I have a 1986 Ranger 2.9l 4x4 manual. It will run way too rich especially when cold. I have to really play with the throttle to rev it up and even to keep it running. I'm pretty sure my vacuum is good. And I changed my ECT temperature and swapped my IAT out. Still is hard almost impossible to keep run when cold. Has a smell of gas in the intake. I've also put a different map sensor on, tried a different computer. If I unplug the ECT or IAT sensors it will run good. I'm stumped on this little guy.
Fuel pressure is good.
Once it warms up it's a lot better but it still has a hesitation and acts like it's flooded
O2 sensor is new a couple years ago. I've only put 80 miles on it since then because the fuel pumps went out and after the fuel pumps went out I've had this issue.
