I removed the coolant temp. sensor that's located at the forward end of the intake manifold. In it's place, I inserted a 155° 3-way CTO switch and connected ported and manifold vacuum hoses to the switch; the third connection going to the distributor. After I had done the nutter, it just wouldn't idle nicely when cold using ported vacuum (essensially 0" at idle). Runs like a champ now. BTW, I like the solenoid idea. I was thinking of doing that for winching operations. Jim 88 Grand Wagoneer 89 Wrangler 00 Grand Cherokee |

From what I have read the sol-vac doesn't have enough power to open the throttle but it can hold it where ever you set it....... now I have to quit playing with it at stop lights :). I also wired my carb/intake manifold heater to the same switch bank and on the really cold days I can flick it on for a few minutes and get the vapors in the intake nice and warm before starting it. I'm not sure where you live but it can get to -40 Deg C here in Alberta and my vehicle sits out in the open when I'm at work for up to 13 hours, it's my version of a glow plug.

I will pass that on to others for sure. I even have my old one kicking around and likely will put it back on. That would be a great thing to have when the idle tubes plug up and it won't idle for crap but runs good over 1200 rpm or for winching. I got a manual choke kit from Canadian Tire and put it in mine. That way I can drive away in the real cold without having to 3 foot drive the thing until it warms up. The electric choke is just a plain timer that goes off according to how long it has had 12 volts, no matter the real temp. I can set a fast idle by pulling on the choke when I have the pedal down where I want it, then letting off the pedal and pushing the choke back in. It stays on the fast idle cam until I blip the gas pedal. Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's |

I have also read somewhere that someone put a reostat on his choke so that he can vary the opening, I thought to myself there is a guy who is thinking. I looked at the sol-vac not as a useless piece of junk under the hood but as an opportunity. :) |
