1994 ST Manual Won't Shift Smoothly? Options

[chrisbf429]

I HATE being the guy who has to start a topic for troublshooting something like this... but here we go.

I have a 1994 ST Manual that I've been trying to get back on its feet. Recently its started jerking and stuttering while accelerating. My alternator starting failing so I figured once I got it replaced it would hopefully fix the stuttering. Apparently not, now its worse. Anyone else ever have this problem? I'm 99% sure the alt works fine and that its installed correctly, car still starts and no issues w/ the battery.

Also just had the clutch replaced 2 years ago so I really hope that isn't the problem. Any ideas!?

To test your clutch get it up to about 35 and throw it into 5th. If the RPM's jump up without gaining any speed it's time for a new clutch.

Dang alright I'll give that a shot on my way home. I appreciate the input!

[chrisbf429]

Clutch seems to be working fine. I'm worried theres something wrong with the steering as well. Theres a constant tug to the left and right. This car is more of a fixer upper than I was led to believe. Well thanks for the suggestions! I'll have to just take it into a shop or something sometime, scares me just as much as going to the dentist

Does it have any check engine codes? Check to see if the cel light is working by looking at it when you turn the key to on position. If no cel codes, get a timing light and check the timing. Also inspect distributor for any wear. The coil pack and wires.
Im pretty sure if its stumbling then the cel would def be throwing a code. Also, it doesnt hurt to give it a minor tune up. Spark plugs and wires, oil change, ect. The basic maintainence work.


Is this a hatch or coupe? Im not that far from you so if its a hatch... Id be glad to take it off your hands:P

Before taking it to a shop, I'd say start more simply. Jack each corner and wiggle the wheel. See if there's any play.

So its shifting smooth, but sputtering during acceleration? Or are you having trouble getting into gears at high RPM, or any grinding? Cause the title states won't shift smoothly, but your issue doesn't sound related after reading.

Also the pulling could be many of things, just have to get down there and see whats wrong. Check to see what needs to be replaced before you go for an alignment.

No check engine codes at all. Just put in snazzy new plugs and wires a few months ago. I'm actually considering selling it sometime soon, it is a coupe though. Love the hell out of the car, refuses to die no matter what happens to it, its just time for a new vehicle.

Will do.

I guess what I mean by shifting smoothly is that after the car is in gear and I'm releasing the clutch, it'll shake or lurch forward then accelerate slowly. It's difficult to explain, it feels like I'm not giving it enough gas but that shouldn't be an issue.

Might've found the problem, bought the car from my father, according to him the rear strut mounts are rusted like crazy and the timing belt needs to be replaced.

Suspension wouldn't have anything to do with the car stuttering, now timing on the other hand would.

Check your fuel pressure, and timing may be a key to it.

Eh I was figuring it could be why it feels like the wheel is tugging left and right when i turn and such. But yeah I'll be getting the timing belt checked out. Lasted 160k miles. These celicas are built like tanks

[Box]

Oh yeah, that. I was thinking solely on the other. If you have time this weekend just give everything a good look over.

The timing belt would cause problems if it let the car jump timing.
