Re: Start up problem with my Geo Tracker
As I understand what you say, the vehicle loses power under load, until it is warmed up?
Two possibilities come to mind: Either you have a sensor problem, like your O2 sensor on the exhaust manifold, that is feeding bad information to the engine computer ECM -- OR -- your engine is worn to the point where it has no cylinder compression until everything inside is hot enough for compression to improve to the point the engine runs okay.
I would have a cylinder compression test done and have the sensors checked.
Also, we are a pretty nice group here. New users are reluctant to put much information into their profiles because of all the horror stories one hears on the Internet. Once you see we are a bunch of pretty nice guys and gals, we hope you'll fill in your profile here so we can be of more assistance to you -- especially the ability to email or Personal Message you.
