one minute it runs good, the next not. mostly pops while second turbo kicks in, now today, it makes 11 psi in first, second turbo kicks in, and drops back sometimes to 2psi. sometimes it makes 6, but as revs go up, it seems to drop. then sometimes it will hold 10psi. but not often. just no normal operation. i never know what is going to happen. i have tried to let off and make vacuum, nothing different. shut car off and tonight it made 3 more psi. (was making only 7 through the gears) i don't think its a vacuum line or hose, i think an electrical actuator,





any thoughts would be appreciated.........



so far, got beat by an old camaro.. dont' want this to happen again....

 

There are not electrical actuators. There are however electrical solonoids. Could be a sticking actuator rod or a failing solonoid.

Most likely the latter of the two.

 

make your car non sequential and get rid of all the transition problems

 

sorry, but you are going to have to be real specific with me.. telling me there is a selonoid to replace, who knows which one i will do, pre-selonoids, actuators, etc.. i get confused...i'm understanding the whole process a bit better, i think after 3 hours.......
