Hello Guys,
I have a 1991 ls400 with about 162000 on it and I need to get to the bottom of a couple of things. 3 things actually:
First, my car seems to have no alignment on the highway. My friend worked on my car and while he was under there he told me that my sway bar bolts were just hanging and he would screw them in . He told me later that he tried to tighten but they had nothing to tighten to. What can be done to get them tight again.
Next, my car seems to slow a lot as if i have the overdrive on when i coast at speeds around 60 or more on the highway.If I step on the gas it picks back up fine but if i coast, it slows like i was slightly breaking. I know for sure the overdrive button is not pressed in. I had the trans fluid changed to synthetic about 8 months ago. Gears change fine otherwise. What else could this be.....?
Last , i get a lot of fumes in my car most days and few with out. I have a code 71 right now as well when i check the codes. I have reset it and it came back on in an hour of driving. No noise besides maybe a light flutter on accel and i dont see any performance being effected. Just lots of rich fuel fumes and the light. I need to figure out how to tell myself if it is the egr pipe, or gas tempature sensor , without paying for both, or something else it could be. I took filter out of the vacuum mod and replaced with sponge material for now. Help....?
