Remembering a car on my interstate commute, saw it many times, probably could only do 45 or so in a 65mph speed limit. Large sign on the back, “Pass Kindly Please”
Until he is able to do a compression and vacuum test, there really is no point in continuing.

A vacuum leak is what I was thinking myself. It made my old 1977 Chevy hesitate, too. Was an easy fix, a damaged rubber hose. Hope yours is as simple. Please come back and tell us what the final fix was.
I don’t
I drove a 1995 Corolla for many years
I know exactly what it looks like
Three starting points: 1- Don’t just guess and throw parts at it; 2-Don’t assume; 3- accurately state the problem.
If it “sputters and chokes” when gas is applied, how is it being driven to know it gets 25mpg?
Like almost everyone has said, check the timing, fuel trims and vacuum. Clean the throttle body that could be failing to satisfy fuel demand. Stop rejecting suggestions because the car worked fine a year ago. And if you are serious about keeping this car forever open your mind to the possibility of a replacement ECM. My qualifications: I have a 97 Civic daily driver with 450,000 miles.
After 85 replies, and an excuse not to do almost every suggestion, I too begin to suspect this thread is a hoax.
Why would I want to see a picture of a 1995 Corolla ? And if I did Mr. Google or Cortana will find me one.
I’d be interested in hearing the engine when it bogs down.
So a video could be helpful.
Well, two things, Volvo. I get quite a few wacky posts. Secondly, think as you will.
What I was hoping for was an “old timer” who worked on these cars ('95). As I’ve said, I think it is (was in those days) a common problem. I’m getting some folks who don’t know what they’re saying or not reading closely what I’m saying. Oh well.
Seeing is believing.
See? There we go, barkydog.
Thx, steve_k, will do, when I finally figure it out. But I notice that no one has commented on the obvious electrical/sensor/ECM/harness problem I mentioned. That is, the speedometer does not show (or register the actual speed, but only a lower speed). When I’m doing 25-30 (I know from the police speed monitors they put up here and there) the speedo reads 5 mph. After about ten miles when the engine has heated up the speedo reads a bit higher, but still not the actual speed (I can tell).
This is obviously not vacuum or compression. It’s something electrical. As noted by me, I changed the VSS two times (one Upick, one brand new). No change. I changed the instrument cluster twice (both Upick). No change. So that leaves ECM or associated wiring. I’m not really competent to t/s the harness.
So, being on a very tight budget I am seeking to rule out the unlikely things and focus on the likely to pursue. Makes sense? That’s why I’m wondering, why would a warm engine make the speedo read closer to normal than a cold engine?
Did you get the problem solved? At one time after a coil replace I had a similar problem, it ended up that the coil ground connection terminal was turned upward a bit to much and when the engine was under load or higher rpm, the spark would ark to the rotor and act like a rev-limiter. Good luck
We are all seeing all of your posts.
