Ok, I am a negligent LS owner, I must admit. I am not a mechanic, and this is my second car. I believe in my ability to fix things and I do have the sop manual for my car. My car has not been running very well, I've had a CEL for a couple months now and much like my taxes I have ignored it. Here's a list of my problems.
1) CEL, dealership scan said Bad CATALYTIC CONVERTER on the passanger bank.
2) Car has a rough Idle when stopped. It also has a hard time cold starting, sometimes I have to pump the gas when cranking to start it. Also when I turn the wheel right on start up the RPM's drop signifigantly and the car has stalled out on me a couple of times.
3) When I drive in the city (not on the highway) the car overheats. The temp gauge goes all the way up. After I park the car the coolant overflows and there is a big puddle on the drivers side under the wheel well. The thermostat has some coolant on the housing, so I think I will replace the thermostat.
4) I probablly have some suspension issues (ball joints) and its really rough when I hit potholes.
5) Weather stripping is falling off my doors.
Basically I've done some research and I came to a conclusion about the CATS. I think that the bad cat would explain the rough Idle and the loss or power on steering etc and might be responsible for the overheating. If the cat is clogged then The exhaust is not flowing and is causing the engine to choke and overheat because the exhaust gas is recirculating back into the engine. I want to replace both cats with Universals (because they are much cheaper) but I am concerned that the O2 censors might be bad as well. My exhaust is stock except for the mufflers and they are welded up to the car via some metal piping....so any exhaust work is gonna involve cutting and rewelding the mufflers on. I want to do some vital stuff while i'm at it (like replacing coolant hoses ets) I'll check back in later, I gotta go to work now. I live near NYC btw if anybody has a shop or anything that could be helpful. Thanks in advance.
