Hello, got a 96 Tracker 2WD softtop, 5 speed manual transmission.
I've noticed that after the car is warm, I hear a very weird static, intermittent "ticking" sound. The sound usually starts ticking as soon as I press the gas pedal from 0 to 1/4 throttle. Anytime I'm past 1/2 throttle, it immediately goes away. Every now and then, when the car is not moving and in neutral, the sound starts right up and ticks for about 5 seconds before immediately stopping
The sound ticks at the same frequency and loudness, and sounds almost electronic (does not sound mechanical at all). Sometimes I can even control the sound when driving slowly (no throttle no sound, suddenly press gas a bit, and sounds immediately starts). I'm thinking it is not mechanical because the sound does not fluctuate with RPM. The sound seems to come from from in front of the passenger side dash, around the engine. I can't locate the sound perfectly because the sound mostly comes on when I'm driving.
SO - I'm thinking that maybe the sound could be my fuel injector(s)? There are 4 injectors, and I was thinking of replacing them.
I found these injectors on Motor Man (can anyone vouch for the condition of these? are they refurbished? They are only 35 dollars each):

I would also get the injector O ring kit from Beck Arnley, seen here:

When replacing the injectors - I would depressurize the fuel system, then remove as described in the manual. Would I have to drain the coolant and remove the throttle body as well?
Thank You
Sina
