So when I start my engine it'll take a few cranks to start but if I just turn it to on and let it sit for a a couple seconds it'll start right up. Would that be spark plugs needing a change?
Also, when the engine is running (more so for the first 10 minutes of it running) the engine "pulses". The rpms will go up and down in a 200rpm window. For example it'll go from 600 to 800 back to 600 and so on. I threw some fuel injector cleaner in but it did nothing.
Can anyone shed some light on this for me? My jeep has 46,000 miles btw.
