I'm trying to do a tune up. I disconnected the negative terminal from the battery. I then tried to disconnect the electrical connection wires. However, they will not budge. Any suggestions on how to disconnect them?

Why disconnect the battery? Usually with a tune-up, you don't have to disconnect the battery. I'm not sure what electrical connections, you are talking about?

Basic tune ups include spark plugs, Plug wires if equipped, fuel filter, air filters, engine oil and filter, and inspecting brakes and belts.

Hello,

There are a few levels of tune up that you should consider when doing a tune up, first what kind of parts are going to be used, next what actions will be preformed such as throttle bore service etc.

Here is a typical guide on the right way to do a tune up which with factory parts should run between $230.00 and $350.00 depending on engine size and type of car.

I recently replaced my plugs, wires, air filter and got an oil change before I took a trip to San Antonio. It ran awesome after the tune-up and on the way to S.A. Later that night, I was driving on the highway and lost most all acceleration and it was hard to get the car to accelerate past 60. I immediately exited and pulled into a parking lot; where I noticed the car lagged from 10 mph to 20 mph. Now when I hit the gas it seems to not want to accelerate and then BOOM it takes off and repeats the cycle. I double checked all the spark plugs and wires and everything is in order and looks right. My next step is to change the 02 sensor. Am I correct about this? Or possibly something different?
Thanks in advance for any advice.

I question the O2 sensor. Has the check engine light come on? Also, check the catylatic converter to make sure it isn't starting to plug or has come loose inside.

Let me know.

Thanks for the response.O2 was not the answer. We ended up taking it to a mechanic and found that it was indeed the cat. Converter. It was plugged up pretty bad. The check engine light came on and turned off.

If the idle is going up and down, check for vacuum leaks and check the idle air control valve (IAC). It is located on the throttle body and is responsible for maintaining a steady idle.

How can I tell if my car needs a tune up. The engine doesn't sound smooth running, actually is sounds like it's clunkly. If that's a word!

Well with 96,000 miles on it, you probably most likely need a tune up if it has not had one in the last couple of years
