Ford RangerMore than two decades ago, the Ford Ranger debuted as an answer to various compact pickup trucks being made available by Japanese automakers. The Ranger was cleanly styled and offered with a choice of a 6-foot or 7-foot bed. Ford boasted that the Ranger had more interior room than the best-selling imports and that 4-by-8-foot construction material could be carried in the bed.
just bought an 87 ranger 2.9 that was cheap, but obviously not well cared for. It starts right up, and sometimes runs for 15 min great, and sometimes it will only run a few minutes. It runs fine, then starts to idle rough and eventually stalls out. I found that the "carbon canister" located on the drivers side of the radiator had been tampored with by the previous owner. It seems like there were 2 plugs on the top that he had cut off, now leaving 2 open holes in the top of the can. When i plug the holes with my fingers the engine idles fine, when left open it tries to shut off....... Should these holes be pluged air tight, or should they be slightly vented???? a new can cost like 90 bucks so i dont want to replace it unless its a must. Any ideas?
Basically they are making a vacuum leak. If you are environmentally friendly or you need to keep your vehicle inspected i'd reccomend either a new or used canister. If this isn't a concern then just plug the lines off.
Get ready for the 351 boss build this summer, 4v closed chamber heads, 2.25/1.75 valves, .750 lift, 12.5:1 piistons, wieand tunnel ram, nitrous, I think its gonna roar!
i found by looking at my 92 2.3 that the carbon canister has 2 plugs in the top that seem to be vented and not totally air tight. Would it hurt to just plug those 2 holes up air tight. I should mention that the hose running to the intake/throttle is intact with no known leak, and the hose running to the tank is hooked up to the can and looks good. I just dont want to plug the 2 ports up air tight if it will hurt the truck.

if the engine runs smoother when you plug the lines that means they are being a vacuum leak.
As far as I know, just plugging the lines off won't hurt your truck. It is somewhat bad for the environment. The charcoal canister absorbs any fumes in the intake of the engine, when its not running.

Cool bud, thanks for your help. Im going to try to plug them off tomorrow. if the engine runs right, then i know it was the carbon can and the vacuum leak. then maybe i will head to the local junk yard and try to find a decent used canister. thanks again
