I changed the spark plugs manifold gaskets and coil packs. Also, cleaned out the throttle. Car now barely drives. Huge vibration and does not pick up over ten miles per hour. Put the old coils and spark plugs back and the same thing is happening. What is going on? Someone told me it is the timing chain? The car is trying to start but it does not.
Thanks in advance.

Good morning.

Did you have this issue prior to your repair?
Is there any stored codes?

Car was a little hesitant. No biggie. I had not done the tuneup ever so I decided to do it. After the tune up ran great for about five miles and then the problems started.

I would start with a compression test and a fuel pressure test.

Also, could be a clogged catalytic converter.

Unfortunately you can not. You replace it with a new one.
