1996 JLX Sport #2 Cylinder Tale of Woe
#2
(12-21-2020, 09:30 AM)LMBaker Wrote: Ok here we go again. was driving home the other night when all of a sudden the sidekicks starts running rough as hell and hesitating. I limp the suzuki home one 1.5 miles or so. Today I have time and its not raining so I start trying to diagnose the problem. I figure its a burnt spark plug. I pull all the plugs and sure enough #2 is torched. I swap that out. This doesn't fix the problem. Still running bad and I have a constant knock very noticeable . start thinking I got a bad boot or a bad cop so I swap out the cop with another cylinder. to see if I can make #2 fire and cause a miss fire elsewhere. This doesn't work. still #2 is the problem. Beginning to think I have a bad injector. Any advice would be helpful. Confused

Also have a cheap code checker currently showing no codes even tho there is clearly something going on with #2 cylinder
cheap reader can not do pending codes, but misfire code to store (dome fuse not blow) can take 2 driving cycles.
the first step is , do a compression test,  done sparks out, throttle blocked open (by foot or hand) and let the needle peak, cranked.
bad valves happen,  no need to spend a fortune first on parts,  just do the test. for sure #2
normal PSI is 199 PSI. on the j18,   has high CR, compression ratio,  so is nice and high. (more power from engine too)
photos of #2 plug are like magic, seen, they talk and tell a story.

knock are not a good sign and bad spark and bad injector do not knock they only misfire, skips a beat and engine shacks a tad. each mis.
the tool is $20  and will not lie to you.... trust your tools.

burrr , shortest day of the year, 21 dec. north of equator. burrrrr no fun working out side... I do feel your pain.....
