I recently installed a MBC and it's currently turned to stock boost levels around 20PSI. The car has not been tuned yet for the MBC alone but its been tuned for my TBE and cone filter.

Twice now my car has stalled on me while driving at low rpm's. I don't think its the battery cause that's working totally fine.

After it stalls I turn the key and it takes a while before it will finally start up again...

could it be the fuel pump? That would surprise me because Im not at high rpms when it stalls so the fuel should be available...

Any input would be greatly appreciated. Thanks!

 

try reving highier when you take off. The battery would have nothing to do with it after the car is started, its all in your alternator. That is wierd though.

 

could it be the idle speed? Is there another way to check if you're alternator is bad?

did you change the bov?

 

BOV is stock

 

Perform a boost leak test and pull the plugs if you don't have a tactrix cable...get one.

 

Make sure the mbc is installed correctly and there is no vacuum leak related to the install.

 

ok updates I think it was my coolant level, I had a coolant leak that I fixed and looked today at the coolant overflow tank and it was basically empty. The car is overheating. I added coolant but it is still overheating and the fan is working fine,

I'm going to try to add some more coolant directly to the radiator and see if that helps.

 

make sure you dont have a blown head gasket.

 

how many miles.... Thermostate might be done if everything is working but its over heating...

Call me when you can

Updates: turns out it looks like it is indeed the radiator leak. New coolant added and holes patched up. Coolant temp is normal now. I will keep everyone updated in case someone else experiences this problem. Thanks

 

First off a BOV wouldnt make the car die lol....Secondly you could check your MAF Sensor...sometimes they can get dmaaged or clogged....or your MAP sensor those are comon problems when stalling at low RPM....If it were a fuel issue you would see it all across the powerband..

 

What temps were you hitting when you were "overheating"? How did you know you were overheating?

I was referring to the overheating of the coolant temps, noticed by the gauge. I have since leveled out at proper coolant levels, both in the tank and on the temperature gauge.
