I have a long standing problem that is getting worse. The engine runs poor under the following conditions-end of cold start to full temp engine has poor power between 1500 and 2500 rpms. worst at 1750. It suddenly will run proper as the rpms get close to 2500. On cold start their is no problem-fully heated mild problem-in between it's bad. No codes- The problem is much worse if their is a bubble in the cooling system.
I have for one reason or another replaced the following with no effect to this problem
fuel injectors
fuel pump
engine coolant temperature sensor
exhaust sensor
brain
It seems like I am running lean or mistimed during the 1500 to 2500 range and when the temp is intermediate it runs badly, may misfire, ect.
