206 gti idle and running problem
Discussion
I have recently replaced the engine in my 206 gti 138 ew10j4 72k engine that was running well in previous car.
Problem is i forgot to connect crank sensor originally and car wouldn't start.
Plugged crank sensor in and fired straight up and was really really smooth then........
The new problem. After 5 mins of running it starts to run lumpy and progressively gets worse to the point 10 mins ish later it will stall.
If i hold the revs at say 2k revs, the revs slowly drop off and if i try to further rev it it will try to die.
What i have done-
-changed map sensor
-cleaned throttle body and idle control valve and other sensors on tb
-changed temp sensor
-cleaned egr valve
-fitted brand new crank position sensor.
-put my fault code reader on and got po170 fuel trim malfunction, cleared codes and it hasn't returned even though issue still remains!
-tried ecu reset following the procedure of disconnecting battery etc.
Really want to sort this issue as it runs so sweet on start up.
