I don't know if anyone here is familiar with the power steering pump and it's assemblies for the 96 Surf with the 3.0l diesel. But yesterday I was out having fun on Yankee Hill, when I got done and on to paved road again my Surf was acting funny, if you tried to accelerate more than probably 30% throttle it'd bog down and get jerky / start kind of bucking, then it'd blow white smoke from the exhaust that had me worried that I blew a gasket or something so I stopped let it cool down checked the oil checked the radiator didn't seem like anything was mixing, tried driving it again started doing the same thing.
So, I decided well everything has good fluids and I wanted to get home and it was mostly down hill so I did drive it home about hour and a half during that drive I learned you could get up to about 75 80 max if you did it really gently with the throttle. So what will happen at basically any speed is if you give it too much throttle or you get to a speed that requires a lot of throttle/power then it starts doing it's weird thing acting up, the check engine light comes on and it's not happy and will be very slow to accelerate or at 70+ will slow down even at full throttle. But, let off the throttle maybe 10 seconds check engine light goes away and it starts running good until too much throttle is given again.
So, the title mentions the power steering pump, when I was four wheeling it something happened to the power steering pump because it became hard to steer, but the brakes still work fine. I was googling it and according to Google's AI, the Surf has a power steering pump that's either connected in some way or built in with the vacuum pump not sure exactly on that relation, but when the power steering pump goes bad it causes the vacuum pump to stop working or at least working properly because it looses vacuum. So what I think maybe is happening is the vacuum pump isn't controlling the turbo correctly so when I put too much throttle and it tries to build boost it can't? Am I correct on my assumptions that I just get that power steering / vacuum pump replaced and that'll probably fix it? Because going up the mountains I had power steering it was making a very faint power steering noise when turning at low speeds nothing crazy and I had plenty of turbo / power to get up the pass, but then after stressing it out too much off road I assume it broke it or maybe a hose or something got too much pressure? It's kind of weird because I can drive it 75 mph without making the check engine light come on or acting up, but it's only when I put too much throttle on, could be at 75 mph or could be at 40 mph.
Being a 96, and OBD1 under the hood I can't just hook up a computer to scan it and see what is causing the check engine light. Because if you try to stop or just let off the throttle the check engine light goes away. Unless the code is stored in the system? I don't know how OBD1 works too much I know you have to jump certain pins and read the flashes like an SOS system lol.
But anyway, I think I'm correct in assuming I need a new power steering pump, clearly I need one anyway because it's not working for the steering just not sure if / why / how the vacuum pump is involved in this and if I should also get a new vacuum pump or if the new power steering pump will fix the whole issue?
Thanks.
