I would like to try sea foam in my engine; I get the part of putting it in the crankcase via the oil fill cap. I also think I understand the proceedure of pouring slowly into the brake boost line but I just don't know where it is... so could someone kindly point it out for me?



Here is the reason for the Sea Foam... '00 Trooper 3.5L with 109k; replaced engine at 66k. I noticed right after refueling this past weekend that the vehicle would have a slipping sensation when starting from a dead stop and then another "shutter" around 30-35 mph when applying light pressure to the accelerator to maintain speed. Much more noticable with the trailer in tow (4,000 lbs). I figure transmission, take it in and the shop says nope it's the motor; tranny is tip top. No lights on the instrumentation panel and no codes in the computer. So I figure bad gas, I'll treat it with some Sea Foam and see what happens. What do you folks think?

One more question about Sea Foam... will using it cause the check engine light to come on? And if it does will it go off once you have burned / drained it all out?

Thanks in advance,
