Check engine light(Seafoam)

[Wailuku4runner]

Hey guys! So I just did my Seafoam yesterday 1/3 thru the brake booster and the rest in the crankcase. I drove it for about 80 miles then changed oil. Then today after driving the runner around for awhile my Check engine light turns on? I have a 1997 4runner Sr5 with 155,000 miles well took care of. Would you guys be able to point out why my light could be on?

Until we have a code, your guess is a good as ours..


I put $20 on fouled o2 sensor.

Most auto stores loan you a reader to run out to your truck and check it.

Swing by one and come back with the code. People can help then.

Cool thanks guys I'll do that first thing in the morning. I just disconnected my battery for 5 min and the check engine is no longer there! I did some research on seafoam and a lot of people said its their o2 sensor. Thanks for the feedback guys!

Same thing happened to me when I Seafoamed. The check light was on for 2 or 3 days after as I started to freak...but then when all of the Seafoam was burned out of the cat and sensors the light went out automatically.:frog:
