Great site and I am new here so this is my problem: I have a 2000 mazda mpv lx - miledge is 120k ( i am the second owner)and it has begun to hesitate and surge under acceleration, driving down the highway is ok but stopping and accelerating it sugres and hesitates and you have to hold the brake to keep it from taking off. Ihavethe following codes: P0106 & P0302 which is a possible MAP sensor problem & #2 cylinder misfire. Is it the MAP sensor? or posiblya bad plug on # 2?
looking for advice before I open the walletand cry.

 

Would definitely look at checking and replacing the spark plugs and proabably even the spark plug wires with that kind of mileage for the P0302 code. If the plugs are original then they would be throughly fried by now. Wires as well.
Check the link to another thread about the MAF sensor. You first want to make sure the vacuum line near the EGR valve that would be going to the MAP sensor solenoid valve is even connected and if so is there vaccuum at the port the line is hooked up to .

Thanks for the reply babyhuey I will be checking this out ASAP! and let you know what i find.

 

I did have a bad wire to #2 so I went ahead and replaced the whole set and the plugs ( they had about 30000 on them from what the previous owner told me plus I have all there reciepts from all repairs done to the MPV). This solved some of the problem but not all it still has a slugish low end until you get it past 40 so I looked at the EGR and found no vacum coming atthe EGR valve port at all - put a drill gage into it and got some debris but still no vacum - also I can see a lever under the manifold on the same side as the egr but towards the front has come disconected and i am not sure what it does and it needs a special clip to hold it back on.One other thing I noticedfrom the repair reciepts is they had the intake taken off and cleaned awhile back so I am wondering if something could have happened back thencause the EGR to fail? - those puppies new are $237aftermarket

Any advice will be greatly appreciated.
