Rough idle & speed varies at speed after warm

[lynn123]

I am original owner of 94 Q45A (104K miles) A few days ago i was goingabout 80 when car started slowing down,it seemed gas starved. after a few miles everything seemed OK,Although this problem comes & goes i suspect fuel pump or filter. After warm it rough idles too.I am new to forum so excuse my ignorance.

I suspect fuel pump as well. It will slowly degenerate until the car is undriveable, and it may burn out the fuel pump controller as well, which costs nearly $400, if not tended to.Another suspect is the MAF connection. Try wiggling the MAF connector above the airbox when symptoms occur.Fortunately for you you're near one of the best shops in the country for Q45s like yours. Look up T3 on South Cobb.

Yep, call T3 in Atlanta 404-794-7700. They're off the west 285 loop, right at the South Cobb exit. These guys work on Q45s all day long, every day, reasonable shop rates, true experts.

BTW, you have a very NICE car with that Q45 Active suspension.
