Is there a way to test the lambda sensor, and to test whether the signal reaches the ecu? I'm boosting around 0.8 bar and when the engine is at normal operating temp(if I've been driving around for a long time) theres a lot of misfiring and hesitation. When the car isnt very hot or the weather is wet or cold the problem isnt that bad. Tested resistances of coolant temp sensor, seems to be fine. My fuel pressure is at around 3 bar (modified standard fpr). I'm not hitting fuel cut and from what I've been reading around here it could be overfueling as there is quite a bit of blackish smoke on hard acceleration, especially when it misfires/cuts out. It happens only on full throttle, I can stop it from happening by lifting off a bit, but keeping boost at full, or close to full, not sure.
Would very much appreciate any help! Thanks!
