Engine surges at rpm over 1500

Look for a vacuum leak (lines and intake), Is the engine light on, were any codes present? A faulty EGR or IAC could cause the problem too. Check the throttle cable for any restrictions.

I have 2002 audit quattro TT with 180k miles. When I do a normal acceleration the car surges and rpm drop but pick back up. If I accel hard it runs fine. Also at idle at times it varies 200 rpm like a

this sounds similar to a problem i had. as the rpm went over 2000 the engine would stop for a split second and then kick back in.
after a few days looking my garage finally found the problem was a faulty air mass meter.
this cost me £200 in total to be repaired.

Surging and loud whistling noise

Sounds like a vacuum leak. Check all vacuum hoses on the intake, throttle body, etc. Sounds like one cracked or came off. Post back if you have any questions. Hope this helps.

Honda accord 1996 v6 2.7 liter,rpm gage jump up and down

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
