Question about Cars & Trucks
Can't have air in the fuel rail,the air would blow
out thru the injectors as soon as they pulsed
When you say (I just replaced) does that mean you
do your own work,because if you paid a shop, they
failed to smoke test the repair,road test or anything else
& put the problem in there
Sounds like a vacuum leak but could be other issues,there
before or added to when intake was done
Did you put a vacuum gauge on it
There is a lot on the internet on how to read

The idle may just be a bit too low. Clean the inside of the throttle body assembly with a sensor safe cleaner, and also the idle control valve or motor. The passages under the idle control can get gummed up, too.
Fuel rails do not get air trapped inside, and a bad injector would not get better as rpm's go up. It's probably something else.

spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

Have you heard of Noid lights? You unplug the fuel injector and plug these in and they will light up if the injector is getting power. This might give you a better hint. There are also lights that go inbetween the spark plug and wire. Between these two items you may be able to narrow down the problem to a specific system. I believe that your car has a coil pack. Some of these engines have problems with the crank trigger. I believe it is located on the back side of the motor. If you decide to change it, be careful. I have heard of them breaking into two pieces and becoming a big problem.

SOURCE: high rev problem
this problem I find in alot of 3.4 ltre grand-ams and that is the wiring go to the intake air temp sensor is broken at the connector. the wire will look good but in the insulation it will be broken. just give each wire a tug, if the wire pulls out then that is the broken one.

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.
