any way to "test" injectors while on the car?

[87gninpa]

my injectors have been ticking a lot more thabn usual lately, and i have been having some minor inconsistent driveablility problems. ECM not throwing any codes, and scanner says everything is ok. so im thinking it may be a problem with the stock 169k injectors. is there any way to test injectors on a car, and if not what are some common symptoms of bad injectors or injectors that are "going" bad??

Not really. The method is to unplug the connectors one at a time and see which one doesn't affect the idle quality. The one that doesn't is obviously the bad injector.

The only real way to know what your injectors are doing is to remove them and get them flowed/tested. Wouldn't be a bad maintenance item at 169K.
