Is it worth it to open up the ECU and clean the connections. I have a couple of minor performance issues and MPG is in the low 20's but in general things are running pretty good. Reason I ask is that cleaning connections on the fuel injection relay and fuel pump relay made quite a difference in MPG. Hate to disturb the unit if it may not help since it seems to be a fairly happy 42 year old.




Having fun!

there's nothing inside that would benefit from cleaning. it's resistors and transistors. maybe the harness connector. good luck, chuck.
