Hey guys need some well needed guidance here, I failed my tailpipe emission quite horribly last August and been slowly working on it until now with work and college in the way. The Hydrocarbons were crazy, to pass in Kent county you need 220 parts per million and at idle mine was 1199 and at high it was 2075 PPM. So let me give you the checklist of things replaced/checked and let me know what you guys think.

Air filter
Spark plugs
EGR Valve, solenoid, sensor
ECT sensor
ACT sensor
O2 sensors
Fuel, AC relays
Throttle body, EGR and EGR spacer gaskets replaced (Fel Pro)
Throttle body cleaned out with brake cleaner
TAB and TAD solenoids
14-15* timing
93 in the tank

Next thing I was thinking was buying an adjustable fuel pressure regulator and maybe even replacing the injectors with some OEM 19 pounders.
