Troubleshooting Accelerating Slowly?

This can be a weak fuel pump, a partially clogged catalytic converter or a bad MAF sensor. If you have a scanner, you can read the MAF sensor to see if it is below these reading at idle.

0.8 - 1.2 grams/second (g/s)

Please go over this guide as well:

Here is the sensor location in case you need it. Check out the images (below). Let us know how it goes.

I have put gas treatment cleaner in the gas tank.

Okay, that might help. Have you had a chance to look at the MAF sensor or go over the guide?

I'm looking at the MAF Sensor today I have already looked at the guide for it already so I will let you know.

Sounds good, we are here for you.

So if it's the catalytic converter is there any way I can replace it?

Sure you can replace if you have the tools and want to. Here is a guide to help check to see if the catalytic converter is bad:

Let me know if it is bad so I can give you directions.

The check engine light is back on when I got it tested before I did the spark plugs and coil packs. It was reading the O2 sensor. so, could this be the reason the check engine light is back on?

It could be, what is the code you are getting?

This is what was read off before I did the spark plugs and coil packs.

I also did the 2-cylinder fuel injector.

Yep, the oxygen sensor code can be from the cylinder misfire. Lets remove the spark plug on #2 and do a compression test, this guide can show you how. Also, you can rent the gauge set at the auto parts store for free.

Please go over this guide and get back to us.

Since I did the #2 cylinder fuel injector and the spark plugs and coil packs the misfiring stopped but now the engine light is on and the only thing I haven't done is the O2 Sensors or the MAF Sensor or checked the fuel filter or pump.

Did you clear the codes since the misfire has been fixed?

No the check engine light went off until 2 days ago when it came back on.

This was what the driver side spark plugs look like there's only one new one which is on the far side the ones starting from the right side are the ones that I pulled out of the driver side.

Wow, those spark plugs are worn out! After you replace all of the spark plugs, I would clear the codes and go from there, which could be all of your problems. I would service the throttle bore and replace the MAF sensor as well.

Please go over this guide and get back to us.

What is the throttle bore and where is it located and how do I replace it?

The throttle body is bolted to the intake manifold. Check out the images (below). Let us know how it goes.

Now the last wheel the biggest wheel that holds the serpentine belt is leaking coolant what does this mean?

We only handle one problem per thread, please start a new question for this problem. Please come back to this problem ASAP.
