The last post (removed) didn’t get a lot of traction, probably because of how long it was. Here’s the condensed version.
Here’s the problem:
◘The car doesn’t give as much power as it used to. It happened all of a sudden while I was on the highway.
◘The acceleration is horrible, but speed isn’t limited.
◘Cruise controls, which always worked well, doesn’t maintain the speed I set
◘When going high speeds, there’s a smell of something burning and light smoke comes from under the car. When staying at low speeds, such as 35 mph, there’s no smell or smoke.
◘There’s what sounds like metal rattling when going low speeds.
Overall still driveable.
I replaced all the spark plugs, changed out some transmission fluid with a pan drop, and replaced the oxygen sensor, but the problem persists, except now it’s worse.
Along with the same problems listed…
◘The gas pedal is much easier to depress
◘When the gas pedal is depressed, the car will constantly lose the “grip” and catches back on and jerks forward. (engine revs don’t match the speed I’m going when going low speeds).
Now it’s much less driveable.
I think the transmission has gone bad, but I want to know others’ inputs before going about getting the transmission changed out. Is there anything else I should take a look at?
Any help would be much appreciated and I’ll answer any questions as soon as possible.
