Hello All...all previous posts are more than 10trs+, so that's why I'm re-posting.

Mods: B20b, skunk2 IM, skunk2 70mm TB, DC air intake, ngk wires.

Replaced/Fixed: [spark] distributor, wires, plugs. [Fuel] kemso pump, fuel filter, injectors, both o2, new cat, map sensor, air temp sensor, coolant sensor.

Remarks: cel 170 & 171, rough idle on cold starts, until the car warms up. Fuel trims are high and when Increase rpms the fuel trims increase, so I know its not a vac leak (smoke test confirms). I'm thinking valve lash. I'm totally stuck and 3months pass registration...im totally lost and I may go to the dark side and take her to Acura.

An exhaust leak that seals with heat will cause your symptoms. Check for a leak on cold start.

Checked and found no exhaust leak(s) over by the muffler. I'll have to remove the exhaust mani cover to see if there are any exhaust leaks coming from there.
