Message Hi,
I am getting horrible MPG, like 9-10, running very rich at idle, so bad it won't pass smog. Runs very strong, smooth at 2000+ RPM, lots of power, but doesn't have that low end power, slight hesitation when starting out, it's completely drivable because i've become adjusted to it, but i need to fix this problem.

After some research, I am thinking a have a leaky injector o-ring. I don't want to buy new injectors if I don' t need to, they have 100K on them, although they are the originals.

I am thinking about replacing all six o-rings using the dremel method.

Must I replace all six o-rings or is there a way to narrow down which one? What do you think? any tips or suggestions how to approach this? Also, where do you suggest I purchase the o-rings? and hex head replacement screws?

Thank you in advance. :-)
