Yeah, exact same problem as last time.
When I seafoam'd I let it sit for about 30 minutes, the directions say 5 minutes.
The injectors are the same ones that have been in there since I bought the car 4 years and 40k miles ago. I'd rather avoid replacing these. The smog check is for a buyer. He's fully aware of the condition of the Jeep and the smog issue, but regardless, it's my responsibility to get it smogged before the sale.
Smaller tires would probably fix the problem.
EDIT - Let's say I ponied up the ~$250 for new injectors, is it something I could do in an afternoon? I have all the standard mechanic tools, just no specialty stuff.
