Hey guys, Long time reader here with a problem.
Car is a 1999.5 Jetta. only thing it has is a straight pipe.
Background. I have been experiencing a "limp mode" situation for a while. I would have no top end and it would go into limp mode whenever I got high in rpm.
I read through the numerous threads on diagnosing a limp mode. I replaced all the 3mm vacuum lines (couldnt get the larger 5mm until tomorrow, so will do them) cleaned intake manifold and put a newer clean egr on. put a newer actuator on and have full movement in both the actuator and the turbo vnt.
That seemed to have fixed my limp mode.
But, now I'm experiencing a no power situation that can't be corrected by cycling the car off and on.
It's hard to describe but I have no bottom end or top end. I have no CEL. The exhaust sounds throatier, and my turbo is no longer loud through my exhaust (straight pipe).
I tried the maf with a couple spares I had.. no difference
I replaced the fuel filter with no difference either.
It sure seems like limp mode, but it doesn't go away.
Any help would be appreciated.
