    Why do my 2000 Pontiac Bonneville have a rough idle?
    My car gives off a miss fire code and drive rough as I pull off and smooth out as I drive until I stop again..

      Usually with rough idle, check for a leak of some kind, fuel--egr--vacuum leak. Also, you can clean the throttle-body and idle air system. Was the code a p0300 or cylinder specific misfire? If a particular cylinder, then on that cylinder, check spark--fuel--compression.

      See this link http://www.autozone.com/.../...rGuideContent.jsp

      and look at Fig. 47: 1990 5.0L throttle body fuel injection engine wiring

      The knock sensor is connected to the electronics spark control module ( escm ). Check the grounding on that module and their wiring continuity.

      Negotiate with local auto parts managers to obtain an escm as a loaner for a test.

      I already replaced that module with a new one, and checked wires

      Checked wires and brn ground wire again just now, all checked good, what now? Could it be the ECM?

      1.Using an Digital Volt Multi-meter or a 12 volts test light to check the wiring pink / black, it must have 12 volts with the ignition in run.

      2. Check the wire continuity ( black ) from the connector B7 ( ECM ) to the module. If all's corrected, try the ECM loaner. ( Store managers will let you borrow, i done that )

      Given enough money - you can swap any engine into any vehicle - though this would not be easy.

      So I could make it fit? Say I get an engine for $3000 how much do you think it'd cost for the work?
    • Jimm
      3/23/2014 Jimm
      You could make it fit - depending how handy you are with a welding torch and hammer. New transmission mount, new transmission, new / custom fabricated driveshaft, new / refabricated front suspension and front subframe, new rear differential, new / redesigned front and rear brakes - the list of items is extensive. My guess is somewhere between $25-30,000 in cost - with you doing most all the work.

      Better and far less expensive to place a rebuilt / new engine of the same 5.0 into the 1986 Firebird body.

      Is the fuel fresh? Was the fuel tank drained and refilled with fresh fuel? Also, check the fuel lines for blockage, cracks, leaks.

      This may be related to the antitheft system The system is known for turning of the starter or injectors when it fails. Is there a light on the dash that says SECURITY? This is a common problem worth looking into. http://www.diy-gm-security.com/ or http://newrockies.com/
