obd 1 b18c1 threw a code 3 now it only throws the code in the morning...when the car is cold..it rides perfect..soon as the car is warmed up to operational tempature it throws the code and my car bogs down and as soon as i stop the car it cuts off..also car is hard to start in the morning could it that mean i need a stronger battery with more cold cranking amps??

 

wtf does your sig mean?
You need to diag your problem a multimeter and a helms would be a great start.
Is your car boosted?

 

will be on saturday....

but anyways any input on this freaking MAP sensor crap

 

ttt

 

Get a multimeter get a book and do voltage checks. the book will tell you where.

 

once again...the map checks out good..still throwing Code 3..WTF?? anyone else have any ideas

 

dam i know someone knows..help me plese this code is kicking my *** and killing my gas milage

 

i know someone can help me on this

 

help

 

Do you have access to another MAP that you can throw on ur GSR to test it. Do you have a VAFC or any other fuel controller???

 

yeah i have a fields hooked up to it..im trying to get another map sensor to put on it

 

Is ur field's zeroed out or is it adding fuel or leaning you out any. +'ing or -'ing up too much can cause you to get a MAP code, but yea that's good try changing it out first.

 

ah ha! thats your problem right there. I had that same damn problem with my SFC a long long ago...royally pissed me off when it happend too. It did soo much I yanked that **** out and went with an Apexi VAFC.

The SFC, if it has a loose connection will f'around with your MAP sensor. In my past scenerio, I'd be driving, suddenly my car would stumble and check light would come on, always a code3, so I'd shut the car off while rolling, then turn it back on and it would go back to normal...sometimes it would do it again a couple minutes after, sometimes it wouldn't.

The best thing to remedy this is to solder your connections for the SFC or just get rid of it and go with a VAFC. You can also try putting it in stand-by mode; see if it still messes with your MAP sensor then...
