I bought a 90 GXL last friday. the engine didnt stay on and the transmission is blown. today i figured out why it wouldn't stay on. someone put on a cone filter and left the air pump hose off with fowm stuck down it. i ghetto rigged my S4s air box on and success, but my new major problem is the engine shakes violently. if i tap the gas it shakes the dash in the car. anyone know what may be causing this problem? thanks

Check compression.

Any black smoke?

 

Do any maintenance work on it yet? coolant,oil, plugs, filters, timing? Check those out

 

nope no black smoke. idles high. im going ot change the spark plugs and coolant and such to see if that may help. before i bought it it had sat for a long time. im getting the battery charged right now.

 

If it sat, check compression.

You may have a stuck seal which can be freed. Try searching "stuck seal".

 

ok thanks alot for the help.
