I suspected in the past that one or more injectors are leaking on my car. I find out that my injectors all have about the same pressure drop, and then I clean my temp. sensor and put diaelectric grease on it to prevent corrosion. BOOM, PROBLEM SOLVED! BUT, BUT, same f****ing problem comes back about 2 weeks later, and car drives sh***y like before. Why would it do this? Is there another problem somewhere else in the system that is coming back? Do I really have an injector leak somewhere or some fuel leak somewhere? What is up with this f*****ing s**t? Does somebody, anybody have an idea?

what are the symptoms?

start unplugging contacts. check for corroded terminals. cant hurt anything that way. just fixed a long time issue on my camaro. turned out to be a corroded ignition coil contact. had the wires replaced the year before didnt even think of it. 1 minute with some sandpaper electronic cleaner and dielectric grease. runs fine again.

It is a poor throttle response. The clutch has very little kick. It usually feels like it has more kick when the car runs good. It seems like my car has more trouble with a poor throttle response than anything. Could it be that the coolant temp. sensor needs to be replaced again or something? Any suggestions? Should I do another pressure drop test on the injectors to check for leaks?
