From what you're saying it just sounds like a loose/worn belt on your p/s pump. I believe the little vacuum lines on the pump help to get the engine to spin a little quicker at an idle when you turn the wheel to help compensate for the extra load on the engine. I don't believe they would cause any sounds or anything. Try tightening the belt and see if that helps. Don't know about the coolant or the A/C not working...

about the heat... Even though the valve is closed, only one side of the pipeing is valved, meaning coolant still goes into the heater core, its just not flowing, but if it has a leak it will fill itself back up becuase only one side of the heater core has a valve. Also, be careful, if you didnt fiill the new heater core when you put it in, thats a large amount of air, enough to be freed into your engine and cause bad overheating. When i flushed my coolant i had no heat when i drove off (air pocket). I started feeling heat, cause the air got pushed out, and all of a sudden my temp gauge maxed and my coolant low light came on, coolant was boiling. That heater holds a lot of coolant so make sure you fill it up before driving.

New Porblem on top of those lol

Well seems my car still throws a code 41.... i imagine then that i just need to buy a new TPS, bottom bracket on it is busted so only one screw holding it on lol

However something i did notice, when i put the car in nuetral and push down on the pedal untill car revs to 1600 rpm and hold it there steady ... The rpms will drop then rise/ drop then rise over and over....

Is this the TPS that is cuasing the problem...?

Also 1st 2nd gear car seems to rev higher and pull more soon as i hit 3rd car doesnt want to rev as high or pull as much, even with throttle wide open

well if you know youre having tps problems fix that and go from there. Sounds like the culprit. Surging idle can also be caused by a vacuum leak or maf

ahh ok, Well vacuum lines are good recently replaced and not throwing a MAF code....

I thought TPS was good after i calibrated it but engine still throws code lol i guess its too beat up and i gotta shell out 120$$

Just wanted to know if it cuased those problems
