MAP SENSOR!!!!
If the shop didnt take the good parts off the old engine you may of inherited some bogus parts on your new engine...I always swap everything over because you never want to have to work on a car again after you just did!!!!

When i start my car it revs up to 4000 rpms why does it do this


Your idle may be set to high for one. Two, you may have a bad map sensor. Also, you may have a bad idle control sensor. Anyone of these can cause the problem. Is your check engine light on? If so, get it scanned at Autozone. A code for one of these may come up. I would check these out. More so the idle control sensor. Test them with a voltage meter first and make sure they are getting and giving the correct current. If you need anything else, please let me know. I am here to help. Thanks for using FixYa.

I have a 1991 Buick Park Avenue. Runs rough in


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

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.

1994 buick park avenue, idling up and will not idle down


If it's not sticking throttle linkage, and i assume it isn't because you have an engine light on, it's probably a faulty idle control sensor. You can get one at any parts store, and they aren't hard to remove and replace. The parts guy can show you exactly where it is on his screen.

your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
