Toyota Repair: 94 Camry Runs rough, bremen ga, dennis reid

Question
240,000 miles. ( bought it recently) prev owner said not many miles on engine rebuild. Ran fine whn purchased, but recently has a misfire. Plugs are good, changed air filter, rotor button. It seems like the plug wires are "one Piece" with the Distributor cap. Is that true. Also changed the fuel filter. tried spraying the plug wires in the dark but not able to see any escaping spark..

Can Auto zone put a tester on it and rovide any infomration?

Any help will be appreciated

Answer
Yes the plug wires are integrated with the distributor cap so I would recommend replacing them, the 94 model used the OBD I system which does not require a scantool to be connected, unless the check engine light is on there is no need to pursue this any further, this system is not capable of detecting engine misfires.
