Default 93 Regency--hesitation, buck etc.

Poor acceleration on a '93 Olds Regency, bucks, pops, skips etc... Idles just fine. Bad wires? Faulty Coil Pack? Ignition module? Ideas....thanks.

What have you done to thus far? Are you getting a check engine light? If so, extract the codes.

When does it do it? My first guess would be bad catalytic convertor. Need more info here, though.

Have not done anything to it yet. It does it on acceleration, it pops, spits, jumps. I had this same problem w/ a similar car and it turned out to be the coil packs.....after replaceing wires, plusgs, injector service etc................

My old 93' 88 has the same problem. I changed the plugs, wires, and coil packs. I have also had an injector service performed. None have helped. I think it is related to the transaxles tourque converter malfunctioning.

I had the same type of problem you are describing. I replaced the plugs and the wires....The more I thought about it...it was probably just the wires. The plugs did have about 70,000 miles on them though they still looked fine. Hope you find it.

If you don't know how old the plugs and wires are, change them. Coil pack troubleshooting is in Techinfo.
