I just finished my setup of I/H/E/P and I am running way too rich.. my plugs are covered in black ash, im gettin crappy gas mileage and my car bogs (not throwing a CEL).. would the best solution be to get an adjustable fuel pressure regulator? If so where is the cheapest place to buy em for my 98 lude?

 

B&M is cheapest, but you gotta modify your stock FPR....ive heard that people have been running them for yrs with no problems......so i mean for cost, B&M is the road most of "us" take. otherwise get an AEM rail and AEM FPR and deal with cost .......oh BTW

I have a brand new B&M FPR i am sellign PM me for details

 

there should be no reason its running that rich especially after u added all those air flow mods, instead of lowering the fuel pressure you should look into whats causing that overly rich condition.

 

Ohh i just assumed that ludes with breather mods run very rich and need a FPR to lean it out.. whats usually the main cause of running so rich? (w/o a CEL)

 

could be a sign that your O2 sensor is on its way out.

 

what is p porting?
