the 98 has cops that do not work on 97, (the deleted the firewall ignitor in 97, IIRC the year.)
the only isc or egr test is to remove it key on , and off and see it it cycles it at key reset time. both have motors in side, and will cycle.
the TPS is set to 0.5vdc, (engine hot and any throttle retractor devices not active, ) that is it for J18s.. no feller gage bs.
the engine serial matches nothing, but the year code would be J18Ynnnnnn Y is year. in usa. T=96, V=97, and W=98'
the hood sticker on ours shows spark gap, its not wide like 1999 + its low, like G16s .
open hood look up see that sticker (up and underside of hood is the EPA big white sticker, there, even shows timing settting, using CMP sensor base. as freeze jumper to set timing, still on J18s.
finding connectors is super hard, only off wreck I think.
misfire codes take 2 or more trips
pendings no trips needed to see them.
more fully explain the misfire, driving both when and when not happens, and conditions. hot ,cold, hills, etc.
good luck !
