My problem was indeed the VAF.

Awesome. I have a similar symptom, so will try a VAF. Can anyone confirm if the VAF is the same on the turbo and N/A models?

OK, the problem started to come back. More cutting out under mild throttle. Ran half a bottle of seafoam through the gas tank. Running good so far.

Read another thread that said the baffles under the valve cover could be causing the issue.

Rod, they are different. Check RockAuto's part numbers. Makes sense since turbo volumes flow more.

Cheers. My problem turned out to be ignition components. Replaced everything and we're all good.

Enjoy! My XR2 is under the knife at the moment, pulled the head and found that the oil passage in the front by the timing belt was the leaker I was fighting for most of the last year. Cometic head gasket, ARP headstuds and a head check including valve seals is underway. Hope to get mine going in a few days as well.

blackhandbeagles: car still doing ok or is that stumble back?  sorry after posting that I hadn't been on the forums in months...

i have a much longer post here describing that same issue.  Mine happened to go away after a radiator replacement.. The mechanic also timed the car correctly. so not sure if it was timing, or perhaps ground related as there's a ground wire on/near the thermostat

i drove it for many months without the tps wire connected. that puts the ecu in a 'steady state' mode where it ignores most inputs and does the minimum to make car run. chased my tail on that one for a few years.
