it is not on now but does come .. I think code 4100
just checked code is p0400... have replaced plugs and rotor and cap
This code PCM detected too large or too small an amount of change in the MAP sensor signal. Check the vapor filter near the Manifold Absolute Pressure (MAP) sensor for restrictions, if nothing found unplug egr valve to see if it runs better. If it still runs rough then I'd replace the map sensor. Let me know how it goes or if you have more questions, thanks.
replaced map sensor... no change.... how can you charge me 37.00 for that ???????????
I did disconnect the erg no change.....
Remove the EGR and put a block plate between EGR and intake manifold to prevent EGR flow. If that allows it to run better replace the EGR. P0400 is related to EGR valve so it is either not related or EGR is being pushed open easily by the exhaust. Let me know, thanks.
was removing the egr when one of the studs broke off... about 1/4 " left sticking out... no way to get to it to remove it short of pulling head...iam screwed . wish I would have left it alone !!
I wish there was something I could do, you should be able to get that out without removing head. You could try to weld a socket to the part that is sticking out or use a easy out. Also with just the 1 stud you could still probably get a plate under there to see if it runs better with EGR completely blocked off.
I said no way to get to it, its between engine and fire wall...I just noticed your expertise does not include Suzuki...no need to reply........
