I have a '86 Samurai with a transplanted '96 1.6L 16v. OBD2, No check engine lights. I even got the evap system operable. 4000 miles since swap.
Engine runs great open loop. No Issues.
In closed loop, after coming to a stop, engine idle drops/surges low 100 to 200 rpm. However, upon "blipping" the throttle, the engine smooths right out at 800 rpm. Next stop, rinse and repeat.
Any ideas?
I have cleaned the ISC IAW the directions on Fixkick. Plunger moved under power. No change in idle issue.
The No check engine light didn't come cheap. TPS was bad. EGR sys had to have a lot of love with a total clog at the back of the throttle body. New distributor, original had an electrical "tick" with an accompanying engine shudder at idle. Two downstream O2 sensors to no avail and then suddenly the exhaust note changed one day and that code and the EGR P400 codes just went away. I occasionally will get a P400 when dirt road riding at slow speed/rpm. Daily drive the snot out of it (65/70mph) and it is happy as a clam and doesn't throw any codes.
