93 Toyota Camry - In the 15 days, when accelerating (while driving or on park) my car hesitates, it kind of feels jumpy and jerky. Changed spark plugs last night and thought it was 50% better, but this morning it was horrible again. Bought some Lucas fuel injector cleaner as well, but. Nothing. Replaced air filter, spark plugs and wires less than 6 months ago, but replaced only spark plugs last night.

Hi JAYJR1121,

Thank you for the donation.

Your problem is most likely ignition fault and if the plug wires are after market parts, I would not discount them as possible causes. Check the wire connections at the distributor cap. If you have an ohm meter, test the resistance of each wire. They should have continuity and less than 25 k ohms.

Next to check would be the distributor cap and rotor.

What is and how to check ohm? Plug wires were after market. What am I checking for at the wire connections in distributor cap? Also, if checking the distributor cap and rotor, what will show me there is a defect or problem?

You need an ohm meter to test the resistance. Connect the probes between the 2 ends of the plug wires.

Check connections for looseness or oxidation. If there are oxidation, it means the concerned plug wire or its circuit has faults.

Check distributor cap and rotor for cracks and the ohm meter can be used to test the continuity of the rotor and distributor cap terminals.

Look out for signs of sparkings

Thanks for your help. I didn't think the problem was with the plugs at all (or the wires). So I started googleing and found out the problem could also be related to the distributor. So I took it apart and, thanks to google, there was my problem. The copper cable inside the distributor was all loose and broken and nasty. Bought a new distributor and replaced it last night. Car works fine again. The only think I need to get fixed now is the airbag light that has been on for 3 months now. I had a bad fuse and when replacing it, the airbag light went on and has been on ever since. Any suggestions?

Glad you have solved your problem and sorry for the delay in replying.

An error in the airbag system has been detected and you need to retrieve the trouble code to know what could possibly cause it. Here are the procedures.
