Doh, just bought a 1997 XJ6L which was in beautiful cosmetic condition (despite 110,000 miles). Drove it back from SC to Washington DC and handled great. The next day it stalled twice in traffic. I was hoping this was a fluke. Started the next morning, and about every other time I come to a stop in traffic the rpm's shut down and the car stalls. It starts right back up if I put it in drive, but then when I go to the next light it dies again. The battery light generally comes on as it dies and occassionally the transmission light even comes on. They generally go off when it restarts, so don't know if that's justa fuse. So basically any time I don't have my foot on the gas and am at a low speed it seems to die. Not sure if this could be a fuel pump or alternator. The electronics on the car still work when it dies.

Help! I'm hoping I didn't buy a lemon.

 

Thanks Cadillac,

From what I can derive throttle body build seems to be a common thread, bad MAF sensor or idle sensor as well. Do you think this is something worth taking to a Jag dealer to fix or can a regular garage handle something like this.

 

No alt lights just come one, just the battery and sometimes the transmission light (which really throws me for a loop). All the electronics works, even when it shuts off. So hopefully not the alt as that'll be $600 or more to replace I'm sure. Lead culprits, so far, throttle body build up, idle sensor, MAF sensor, ECM or BCM.

 

My estimate was probably off, I know I have spent $300 or so on previous cars like my 300ZX and was just trying to adjust for Jaguar. Like I said, I'm guessing it's not the alternator anyways. But we'll see when I take it to the shop. I live in Washington DC anyone know of a decent garage around here. I have a decent mechanic but don't know if he knows much about jags, and I definitely don't want to go to the dealer.
