ok i started the car up for the first time after the port an gasket change and now its got a bad idle problem itl start up at 1500 then as i step on the gas itl fo to whatever and bounce back down to 2000 then itl like stumble really low and die it has gas i do need to put about 2 quarts of oil maybe i think that its prolly the idlecontrool thingy i cleaned it out or maybee its that thingy in the front of the im that connects to 2 hoses a small one and a medium sized one that connects to the IM just curious on what you guys think that it is



thanks in advance

 

vacuum leak. Listen very closely to the engine for a hiss. Mostly likely the intake gasket isnt sealing right or you forgot to connect a hose somewhere.

 

checked all around no leaky hoses but i do have an intuition that its the head gasket are you supposed to put sealant on the gasket evev thogh the gasket said not to (felpro) i kno that i tightened thm dotn right
= thees smoke soming from the exaust manifilds smells like fish (antifreeze) fso i think that it is antifreeze leaking into the cyllinder head and burning and when i acellerate and let go itl slow downthen bog like its gonna die then i give it a lil pinch og gas and it idles fine
bcdd replaced along with th idle unit i really need help now...

i did oncr hooked up the fpr wrong once but switshed it back it mde a screming noise but the car runs just dont kno whats wrong

 

As far as I know, you aren't suppose to put sealant around the gasket. Is there coolant in your oil? How does your compression look? How about a coolant system pressure test? Is coolant leaking from the IM or the throttle area? Did you remember to close the bleeder valve for the coolant that is next to the EGR valve? You probably have a combo of leaking coolant and a vaccum leak. I bet your IM gaskets might be leaking. Did you reuse any of your gaskets?

nope all new ones no coolant leak that i can see
