Engine stall


Recommended Posts

I stored the car in the garage for about a month, I disconect the battery,

after this, the car stalls once in a while when I drive on city streets or slow down at a corner.

I can immediately restart the car by placing the gar in second gear and engaging the clutch.

The engine runs roughly and sometimes surges unexpectedly.

Anyone knows what's wrong with my car? Thanks.

My car sat for two days without a battery while I got a new one.When I put the new one in I can't say I noticed anything unusual except the need to enter the radio code.So is it such a problem to disconnect the battery or even take it out if I am away for several weeks?

Hi, Loren

I tried to drive my car, but the car just stalls a lot, can not even drive. It also came with check engine light and ABS light. I had read the codes, one is p0102, the other one is 5525, I have searched the code 5525 is caused by the Mass Air Flow sensor, when I disconnect the MAF sensor, my car just runs fine, should I just change the MAF sensor or it's the ECU's problem? I am using K&N filter now. Thanks.
