Vacuum leak

As mentioned, intake leaks are a possibility, but there could be a fuel delivery problem, a bad ECT sensor, or even a bad DME.

checked for the common vacuum leaks and nothing the ect sensor is the blue coolant sensor? I swapped dme's as well and same thing happened. I opened the original dme and found a bmp design chip in there. Im thinking of swapping the chip as well because i have another dinan for the same ecu number.

how about the O2 heater relay? it's the same kind of relay as the FP. swap them around and see what happens.

changed the chip and got a better idle around 800 rpm. so you saying swap the orange relay with the white relay near the driver side wheel?

swapped relays and the same CEL

i have some vr6 fuel injectors to see if the bogging is due to clogged injectors because i have 235k on the motor

[Goya20]

will they fit?
