all gaskets are good, vacuums are good, egr is working properly and dealership issued, map sensor is new, tps, iac, temp sensor, fuel injectors, and plugs are all new.

so my question is, can a brake booster check valve be at fault if it were leaking?

the brake light comes on after going 35mph and stays on until i shut it off, and my brakes do feel kind of spongy but builds up if i pump it once. ive recently replaced the brakes on all 4, including wheel cylinders, calipers and master cylinder, and bled them properly, about 3 times.

it has never stalled, runs strong at about 1500rpm but bogs on the freeway in overdrive at like 50 and until 70. also throws a code 32 and 34 after ive driven about 20 miles.

thanks in advance

 

no one?
