I purchased this Amigo 4 months ago and it has been running well with few problems. The first problem is that when I'm cruising down the expressway, when I take my foot off the gas pedal after a few seconds it feels like the brakes are being applied and the RPMs drop about 5k. Don't feel any misses or hesitations and the OBDII shows no codes. A few days ago I went to a store and when I came out to leave, the truck started then cut off. It started right up them cut off again. The next time i started it i gave it a little gas to keep it running then put it in gear and drove off. it continued to run but idled around 500. When i got home I let it sit for an hour and went back out and it did the same thing. Didn't have time to work on it that day so after work the next day I started it up and it ran fine. I checked the plugs, hoses, lines PCV and pulled and cleaned the IAC which was filthy. Started it back up and now the RPMs run just a little higher than normal, about 900 warm and 1300 cold until warm-up. But it runs good. Any suggestions?
