One Cylinder Lean
One Cylinder Lean Have just got car running and have made a couple of test runs on back roads and I have one cylinder #5 that is lean. All the others have perfect color on them. I am using a microsquirt with gt45 and 80 lb injectors. I checked compression and all were the same. Rockers are fine pushrods good. What could cause this. No apparent vacuum leak on that cylinder on intake. Could it be one injector is not working right. Any help appreciated.
Could be a vacuum leak. Move the injector to another cylinder and retry. If the lean condition moves with the injector, it's an injector issue. If not, pull the intake and look at the gasket real close.

Yes injectors are new. Have read plugs for years racing and these plugs have nice color and marking on electrodes. This is first ls turbo motor and just looking to see if any different idea on lean one since microsquirt is batch instead of sequential fire. Still open to ideas as I am going to try injector swap tomorrow to other cylinder with different plugs to get good reading on new ones to compare.
