95 Taurus SHO 3.2L Failed emissions badly-
hydrocarbons in grams/mile=1.68 where .80 is pass
carbon monoxide in grams/mile=44.80 where 12.00 pass.
oxides of nitrogen in grams/mile=1.78 where 2.00 is pass.
I have three codes :
O2 sensor lean left bank(but was replaced still has code)
spout grounded
egr valve not opening(replaced still has code)
I checked the egr vac. supply-has vac from manifold to egr control valve on firewall but barely any to egr from control valve. I changed control valve with my 93 SHO which passed with flying colors to no avail.
I also tried hooking the egr directly to manifold vac. and it does change the idle and performance so I believe egr is good.Although I dont know what controls the egr control valve electricly(trying to trace the egr problem)
The exhaust has a very strong fuel smell almost burns your eyes from both tailpipes.
The fuel pressure regulator located on the rail under intake does seep gas.
I have switched the ecm from my 93 with no change so I ruled that out.
Any help here to get this thing to pass would be apprieciated.I dont have the money to donate right now due to being out of work...sorry
I was thinking of taking the manifold off to replace the fuel pressure regulator as i think it may be forcing too much fuel and making the car not pass????
