Is that front CCV vent free and unrestricted? (suppose to be routed to the air cleaner.) If it can't vent blow-by there, it will do as you describe, the leaking that is.

Oh! I read it wrong...thought you were leaking when you gassed it on a hill. You might start with checking fuel pressure. There is a test port on the fuel rail...should be about 31# , then go up to about 39# with the vacuum line off the regulator. I take it your plugs are good at .035, cap/rotor/wires are not the issue?
Not really what you are describing...well maybe...the little tube from the inside of the TB, back and up to the MAP sensor up there on the firewall is supper crucial. The MAP NEEDS to have that perfect to tell the ECU how much gas to dump in there. Usually a problem there makes it rich though.
Whoops, wait, what year?

Since you said you have a Renix. Have you tried refreshing all your grounds. Hell it's worth a shot. Hopefully you can come to a resolve cause 195 is still young

True never mind just re read and saw that. When did this start happening. Did it happen all at once. Little at a time. What kind of oil you running. Seems like pointless questions but hopefully someone sees all this and can come to a conclusion
