Hello people! New owner here. I have a post in the introduce yourself section, but I find myself in need of some assistance. The first time of many I imagine.
So, long story short, I scored a free 87 Ranger extended cab on Craigslist yesterday. One of the issues it was having was that it idled unevenly, and often tried to stall, or race in neutral. As part of the "new to me vehicle" process, I wanted to Seafoam the engine. I got the spray, simply because I find it easier to use. I put the spray tube into the throttle body, reconnected the intake, and started the truck. Using the throttle linkage, I revved the engine a little bit and started spraying. I've done this plenty of times before, so I wasn't really paying attention, until about half way through, I noticed the engine note hadn't changed, and there was no smoke coming from the exhaust. I finished up the can and cut the truck off for 5-10 minutes. When I started it back up, it fired right up and ran normally, again, no smoke. I then noticed some fluid dripping out of the air box... Yep, you guessed it, somehow all the Seafoam (or at least the massive majority of it, ended up being sucked down the air return line to what I guess is the IACV, mounted on the side of the air box, connected to the other end of the return tube. So, WTF? Why did that happen? How do I prevent that from happening the next time I try this?
On a side note, I noticed the vac lines for the MAP sensor were completely rotten and cracked. I replaced those, and it's running and idling MUCH better now. I'd still like to Seafoam it though. Advice?
