1991 niassan 300zx tt idle issues?
Car limps at idle. 800 to 1100 rpms. No other issues. Codes check 55. The only light on instrument panel is for "hicus". Another issue. Car runs great, will idle without dieing, not other problems. Coil packs were first thought, but i have no clue how to check. Should i pull and check each plug individually. Could i run a voltage meter over wire to test for inconsistancies? Idfk. Any suggestions are helpful.
