found out i left a vac hose off of the ps when doing my mounts. only problem is i pluged it back up and it didnt fix anything. car is still surging in neutral and letting out white smoke when giving the car throttle. please help. car is my daily.

Not so much thinking of those 2 lines, but wondering if there are any other lines that could be crossed... you mentioned leaving a vac hose off when doing your mounts. Just sayin, double check ALL the vac and cooling lines.

yep a vac line to the manifold was off. wierd though because i never touched that line. maybe i hit it off, and didnt notice. the white smoke has decreased ALOT, but still at correct temp with throttle some is still coming out of the exhaust. anyone have an idea why, and hopfully not the head gasket

Is it cold out where you are (below 50)? If it dissipates quickly its probably water vapor, a byproduct of combustion. If it has a sweet smell to it, then it may be coolant. Do you hear any hissing from the engine bay? Try spraying some brake cleaner on the vacuum hoses with the car running. If you hear a change in RPM then you know where to start looking for a vacuum leak. Also, did you bleed the cooling system and use new O-rings on the IAC?
