The honda accord I am driving is a 2000 Honda Accord SE with 195000 miles on it. Its a F23 engine VTEC. Everything on it is stock, motor, tranny etc etc. In all honesty, I barely drive it real hard ever due to its age. It holds 80 to 85 mph fine and I can only think of two or three times in recent memory that i pushed it to the limit.

Bout three or four months ago i remember it hitting north of 105 mph before i let go and slowed down. That was me shifting through the auto tranny holding gears to redline. But two days ago, I nailed the car and on flat road it simply wouldn't get past 90 and I noticed all the shifts occurred at around 4000 - 4500 rpm. Wouldn't rev past no matter what i did. In all truth, I barely ever drive past 85 anyway or even at 85 for that matter so it shouldn't matter but I just want to know if its an indication of an oncoming problem. I know the car is nearly 11 years old and got a ton of miles on it but I'd like to keep it going as long as possible. Any suggestions guys??

The check engine light isn't on or anything, never really comes on.

 

Stupid question, but is that the v6 engine? I might suggest checking the compression on the cylinders.

 

Nah, that's the 4 cylinder engine. How do I go about checking the compression on the cylinders?

 

A compression tester is like a pressure gauge that fits into the sparkplug hole.

- warm up the engine
- remove all 4 sparkplugs
- disable fuel & spark (pull fuses, etc)
- insert gauge into a sparkplug hole (rubber end or threaded, depending on the gauge)
- hold gas pedal down to the floor
- crank the starter until the gauge quits rising higher
- repeat for the other 3 cylinders
