New owner here. ~60000Km on my Acty van. purchased it from Houston Tx and had it sent up to CO. I had a friend test drive it down in Houston and it drove fine, when I got it here to CO it would only idle. I pulled the plugs and they were soaked. Read from a popular poster here (Shogun) that the fuel and air solenoids could be the problem. Purchased both with a carb kit from Japan (took about 8 weeks to get here) and pulled the carb. Tested both solenoids and the air was frozen. Would not move up and down at all. I have replaced and will be putting the carb back in Sunday. I cannot pass emissions here in CO. We will see if this fixes it and will update. The van will run fine without the airbox cover, once on it wont move an inch without dying. tbd.
