Testing Injector My car started getting lean, I thought it was a vacuum/gasket leak but now I think its the injectors.
It was mid 13s a/f before I pulled the intake the 1st time. I thought the fast had cracked. After the first pull it went to 16.0(max setting on A/F gauge) at idle and WOT. Its like the power enrichment is kicking in. Only at cruising speed would it be around 14.8-15.3. I was still thinking it was a leak so I pulled the intake and changed the gaskets.
Now it's maxing out the a/f at 16.0 all the time and running/ sounding like ****. I pulled off the # 1 and 3 injector plugs an it didn't seem to change the idle. How can I test my injectors and/or connectors to track down the problem?

What is your fuel pressure? all inj. will not go bad at the same time maybe 1 or 2 at most. But if the fuel pump is failing it will run lean with low pressures.
