Okay so I'm a broke college student with a sc400 so I have to like work part time for a month just to save up for car parts...can't really afford to go to a mechanic nor do I have connections

With that in mind...

Here are some symptoms I a having.

Going past 50 my steering wheel will vigorously shake and so will my shifter. The steering wheel i can see why it would be a rotor since I have a seized caliper(replacing soon). But what explains he shifter shaking hard? Also steering wheel vibrates on take off usually.

When I'm parked and on neutral ad rev it. The accelator doesn't feel normal neither does he front end feels like a "lag" and it shakes the front end a bit.

Can someone help me out and give me some clues on what could cause this ?

Driveshaft insulators? I replace te driveshaft bearing.

Bad harmonic balancer?

Bad torque converter?

 

Maybe the revving in neutral feel and shake in shifter are two different problems?

Could the revving be a coil pack issue or trans mount?

 

Tire balance, motor mounts, steering rack bushings, contol arm bushings all need replacing. If the motor has a miss check spark plugs and wires. Try seafoaming it maybe! Clean MAF also. Check harrness plugs to ensure they are connected firmly and unbroken. Look for vacuum leaks. Thats all I can think of other than checking the ECU on the car for crappy capacitors.

Just a few suggestions not definate answers to you problem though.

 

When would be a good time
