here is the deal i have a 2000 neon when i press the brake i get this shaking really bad, so i replaced my motor mounts brakes and rotors, the car still does it so when i got up on monday to start my car now it wont start i need to know what the deal is, not fuel pump can smell it and not the starter cuz it starts and runs for like 5 sec and then dies need help thanx everyone

There are so many things that come to mind!

Vacuum Leak
Bad Sensor
Clogged Something?
Faulty Something, most likely, get under the hood, and get looking

autozone says torgue converter so im goin to be checking into that, i got the car to start i unplugged the positve battery for a lil bit and put it back and it started

I don't know how well I would trust that the guys at autozone here are about the least automotive inclined people I have ever met. I have a 2.0 highout put injector cover in my 05, and since the rt wasn't offered in 05 he thought I had a srt and when I told him no its just the base 2.0 he said then that wouldn't be on there. He wouldn't sell the a cam position sensor unless I got it for the srt because he knew he was right to the point he told me he didn't want to deal with having to deal with a return when I came back.


As far as the torque converter I wouldn't jump right into that off the bat. I would try the easyer and cheaper possibility first. Vacuum leaks, sensors, coil and wires. I personally have never heard of the torque converter causing what you described.

If the TC is not unlocking totally, it would cause the engine to shake and stall.

Wouldnt that throw a tc code though?

just got back from a shop that test for free and sure enough its the tourge converter cuz the transmission shop said when in 3rd gear its not wanting to release so it boges the engine down but here is the funny thing its not throwing a code cuz i tested that also and the codes there are throwing is p1684 ,p0551,and p0140 which one power steering,one is battery disconnected last 50 starts and 02 senor thanx for all the help checked for vacum leaks have a small one im goin to fix today and the autozone i go they all are into cars there is not one person there that dont have some kind of car fixed up

It will only throw a code if the solenoid fails, as in the circuit is open.

It has no real way to know it it is sticking, or actually engaging. That would require anther sensor to measure the TC rpm vs the TC output.

While there is technically the tach signal vs the input sensor speed, I don't believe they thought of it, or thought it important enough.
