when i start it now it rumbles and gets really loud and revs up for a sec and then quiets down and doesnt seem like its running right. also today when i put it in reverse and i made a loud squealing kinda sound and even in park. so i turned it off and then back on and it seemed fine. maybe its the trans but it shifts alright she just started acting up today ha

 

The reving problem sounds like its a problem with the vaccum system

 

Could be the CKP (Crankshaft Position Sensor)

 

ok thanks that sounds like that might be the problem cus its something with the trans.

 

Your idle is probably acting up because of the Throttle Position Sensor (TPS) and/or Idle Air Control (IAC) valve. Keeping it on the cheap, start small by cleaning the IAC and bore/throttle plate in the throttle body.

That rumbling you hear is likely due to the exhaust pipe resting on the cross-member (before the cat). There's a hangar/bracket located there that can break (it's actually pretty common). If this is true then don't worry too much because the fix is pretty cheap and easy anyway.

 

No.

 

This.

 

i figured out the problem. the bolts for the motor mounts were all broken on the passenger side lol. so i drilled and used the easy out and put new bolts in and it runs good now lol thanks anyway guys

 

Glad you got it fixed!

 

I've never heard of motor mount bolt causing a high idle.

 

depends on how much the engine moves I think...would possibly move throttle cable a little and maybe put exhaust out of line or up against something...

 

Wow! really?

I agree with GEEOH... never heard of a motor cuasing that. Its def not the cps. if it was it would stall or not start at all. high ide or a speratic idle is vac leak or the iac or tps. trust me. you did not fix it. it will happen again. should be throwing a code. get a code reader on it. even if the light is not on, it could still be storing a code.
