Newbie here. Did try searching and did as many Cruise 54 checks as possible.
1989-XJ.
Performed Engine swap. Starts, idles very nice. Crack the throttle and it falls apart. Shaking, miss firing, popping (back fire maybe).
Grounds refreshed at dip stick,
CPS checks out good, (can only check resistance with current meter)
Coil checks out good
TPS voltage correct,
Map sensor voltage good.
Please help
