I noticed that when I ran the sea foam stuff through my motor that there was alot of exaust leaks.when I put my exaust together I was in a rush.Instead of welding the seams all the way around i just tacked the seams on each side(thinking it would be good enough)
Would these leaky seams be giving me lean readings on my A/F gauge.Cannot figure out why it is runnin lean at idle.
