I used this stuff on my wifes car and it seem like it worked ok.
So I figured I try it out in my truck.
Sucked a 1/2 can up thru the vacuum line, let engine sit for 10-15 minutes.
Took truck out for a 5 minute spin around town, and everything seemed ok, came home a parked it.
An hour later I had to run out to the store and when I started it up I notice a rough idle, then a few block from my house check engine light starts blinking then stays on steady.
Truck is idling very choppy now and the volt meter goes crazy if I put the air conditioner on when I'm at idle.
wtf is going on??
fouled plug? sensor?

yeah blinking service engine light=random multiple misfire. my guess is that you sucked up the foam too fast or you had a plug on its way out and the foam did it in. grab some tr55's for cheap and put em in

Is it a check engine light or service engine soon light? They are very different. If it's the SES light, then I'm guessing like the others that you fouled a plug. Time for a plug change. No biggy, $20 and 20 minutes of your time.
It would be the service engine light since that's the only one that's on the truck. I always thought they were one in the same though. I know cars have either one or the other. Some have a check gauge light.
