Pontiac bonnev. 1999 will not pass in. emissions test due to on board diagnostic code po171 system too lean

Check vacuum lines at the throttle body for leaks if good then take EGR Valve off and clean carbon out with a non-chlornated brake cleaner.Then clear code from computer and if it comes back on check the fuel pressure it should be 48-55 psi with the key on and the engine off.If its not within these specs then the fuel pump is weak and needs to be replaced.

Hi, my 01 Bonneville SSEI keeps saying check gas cap, then the check engine light comes on, I have replaced the gas cap and that did'nt fix it. Any suggestions? Thanks.

Hello: You need to find out if there are any codes in the engine control module. Go to a parts store ie: Auto Zone, Advance Auto and have the codes read, they normally don' charge. If the code is for the Evap system have them clear the code and see if it comes back.

How do you pull codes from a 98 bonneville

k, the diagnostic port is located under the dash on the driver's side. Bring the Pontiac to a parts store. They will plug a hand held scan tool into the port and 'read' any codes stored on the car's computer. This is a FREE service. Good luck.

My 1993 bonneville keeps shutting off when i come to a stop! help please!

Could easily be a vacuum leak or a faulty throttle posiiton sensor. Is your check engine light on? If so, I would have the engine codes read to pinpoint exact problem locaiton area.

Try disconnecting the battery for 1/2 hour an then reconnect and drive for 10 miles. It may run rough for this period. This will clear codes from memory.

NY 1996 Pontiac Bonneville SSEi diagnostic trouble codes P0301 and P1441

Since it is a 1996, you probably have high miles on it.
Most cars after 100,000 miles or so are automatically set to have the check engine light come on.
