I bought the lady a 97 se and today i replaced the plugs , wires, and air filter, also changed the oil. It still feels like it struggles alittle bit.
im wondering if thier are any tune up experts here who can help me get it running as well as it can.
please help with knowledge.
 


ok, so I pulled the plug wires one at a time while car was running. 1st for had spark. the last two were dead. took the coils off and removed the ignition module under them. took the ignition module to autozone to get tested. it failed. spent $150.00 on a new 1 and replaced. car now runs like a new one with all cylinders firing. I got lucky and didn't listen to the guys at pepboys.
