Hey guys I have a first gen car with a turbo 2swap. I am having problems with a bad low end miss when I put an air filter on the car. I am also having a problems when the car hits @4200 rpms it bogs and wont rev or excelerate any higher. The strange thing is that it doesnt happen all the time. Any ideas???????

 

Maybe Fuel Cut?
Give us a list of mods and some one should be able to chime in.

 

I had this happen to me once. the car would run fine untill around 4000 then it would hesitate. It was the one of the injector plugs on the secondaries. the plug would wiggle loose and then make a connection again. look at it closely and make sure it is making a good connection with the wires.

 

Ill pull off the plemum and look at the injector harness to see if thats it. As far as mods it has the fuel cut defender installed and GSLSE injectors in the secondaries. The motor has a hugh street port with 3mm appex seals. I am running 2 gslse fuel pumps. I am running about 8 pounds of boost.

 

Anybody/
