Terrible bog when cold

[hubz91talontsi]

Few mods that i think could be the problem

FMIC 3" pipe
MAFT
Non Recirc bov

So when i start my car up in the morning and i try to go it will just sit there for a second. Like it will idle fine but as soon as i hit the gas it goes crazy like its building up pressure or something. Takes it a second then its fine. Don't really understand. May cause me to go back to the stock smic

Are you letting the car warm up before driving it?

 

[hubz91talontsi]

No Should i?

 

[cruisintalonawd]

probably should try it and see what happens. If I try and hit boost when my car is cold then the will be there but it doesn't kick in, like theres an anchor behind my car.

 

[hubz91talontsi]

no no nothing about boost, just trying to get the car to move. As soon as i start the car up and hit the gas it bogs for a second like almost wants to die then it will rev. Like almost a misfire or something.

ccheck your tps and then check for boost leaks

my cars doing the exact same thing. when i give it gas it boggs bad, but if you go real steady it will rev up fine. i just rebuilt the head on it.. im going to replace the plugs, wires, and feul injectors. let you know if anything helps.

 

[hubz91talontsi]

has nothing to do with tps or boost leak. I guess i may have to take a video.

My bogs a bit, it it M/T or auto? It takes a second for the A/T fluid to warm up. Until it does, it's slightly thicker and that can cause some minor bogging, when cold.

 

[hubz91talontsi]

No, its a M/T. Im not saying its cold out side. When i start the car up and try to move it bogs.

Exact same thing here. I also have a maft setup in blow through. Only thing that eliminates it in my case is letting the car fully warm up. Love my autostart.

 

[hubz91talontsi]

Ok so its the maft doing it?

Edit: I do not have a short route btw

 

[da_reeseboy]

How is ## MAFT setup? Blow thru just before the intake? And how recent?

 

[hubz91talontsi]

Yep, how long; no idea since i bought the car.

 

[Daaan]

sorry to be such a noob, but whats a MAFT?

 

[fulanititoo8198]

Search... It is a setup composed of a mass air flow translator and a gm air flow sensor that allows you to tune (somewhat) and vent bov correctly. Has some other cons such as spool improvement blah blah. On the other hand I can't wait to get rid of mine.
