I just picked up an 04 WRX with 32k on it. I bought it about a week and a half ago and Im thinking I might have a couple issues. First, when I'm in a lower gear (1st or 2nd) and just crawling along, If I let off the gas I get a THUD or CLUNKING noise (sounds like its from rear dif or tranny.. cant tell). This also happens as soon as I get back on the gas in just the littlest way. I'm not sure if this is bad bushings, or I'm just not used to the AWD drivetrain yet. This doesn't happen later on while cruising in other gears, seems likes it's just 1st/2nd.
Next, when I'm driving regularly again, and I give it partial throttle (usually from 2nd to 3rd) the engine seems like it hesitates or bucks a bit. I feel it mostly on my gas pedal and I don't get any CELs. I read something about 2004s having a few problems but it seems like they were in the 5k RPM ranger where mine is down low. If I give it more gas then its usually fine.
Lastly, this is my first manual transmission and I need a few pointers. What RPMs does everyone shift at for normal driving? I usually shift around 3k but I want to make sure thats ok. Another question, when cruising a parking lot a very slow speeds, what gear should I be in and is there a way to make it so my car doesnt shudder? (Im usually in 2nd because the car doesnt like going into first if its moving)
I know Im asking alot of questions but I figured Id post in 1 thread instead a a million, thanks!
