Advice needed for v6 turbo cutting
I bought 97 v6 turbo 2 weeks ago and im trying to make a good car,a perfect car. Turbocharger is repaired by repair kit and wastegate changed and now the cur goes like a bullet. But this is the begining of the problems. Because the pressure was very low ,these problems never occured before turbocharger has been repaired.The problem begins after aprox. 10 min.'s later you start the car.At about 4k rpm boost goes down and at 5k rpm turbo cuts in second gear and third (didnt try in the forth or fifth). Then the car goes like a kangaroo with turbocharger.There is no problem before 3k at all,i mean it may be something about turbo.?! The distrubitor and spark plugs may be the problem??? It feels like the electricity of the turbo goes away or maybe something like the gas cuts. Spark plugs are golden lodge and they are not in their best times, distrubitor is very very bad bad....
I really need your advices.
