Hello all,

I have a 2000 Civic that runs fairly well. It only has about 115k miles on it. Got it from a family member that no longer drives. What I notice about it is that when I take off from a stop, I barely press the gas and it takes off really jerky as if I gave it way more gas. And then when I am decelerating from freeway speeds to lower, it has a really strong engine braking around 45-40 miles an hour. Almost feels like someone tapped the brakes hard. It cruises relativey smoothly, no engine codes. I think its all mostly original besides normal maintenance and timing belt replacement. What to check replace first? I thought about getting new plugs, cap, rotor and just doing a tuneup. But seems like maybe more than just that?

Thanks

 

Check if it's had the throttle cable recall done.

 

Is it a manual?

Is this your first manual?

 

Ah ok, thanks, wasn't aware of that. I'll ask him if he remembers or has any paperwork.

Sorry, automatic(I guess 4 speed auto)

 

When is the last time the fluid in the transmission has been changed?

 

The sudden decel could be the transmission shifting down a gear, happens in my 05 from 15-10mph naturally when it automatically shifts down to 1st.

 

those symptoms sound alot like a bad or uncalibrated TPS. but my only reference is in manual cars so i am not sure if auto would be the same as far as those symptoms go.
