problem with my 94 grand prix 3.4,i probally had this problem before,but
with having fixed a quite a bit of other car problems,i need refreshed on
this problem,the car seems to be surging on fresh start up,but levels out
as it warms,i know this sounds like upper intake gaskets which were a
problem on this engine and i have replaced them probally at least 3 to 4
times in a 8 year period,but could it also be a iac problem as well?, even
though the car levels out as it gets warm there is still a slight flexuation
in the engine as it runs,it idles around 1000 rpm and now it surges slightly
around 600 to 1000 at times as it has run,also it has the tendacy to as you
gun it and let off the gas totally the car will want to kill as the rpms go
straight to zero and then catch and stumble as it gets back to normal rpm"s.
any ideas please as i will probally remember as you give your advice,
thanks a lot
