vapor lock ? 89 200tq

[ricksiev]

Well I've tried the professionals, now I will try the best.

1989 200TQ, 168k, WAUGC5442KN098256 - 3rd owner

The Audi is in pretty good shape, upkeep, records etc. No great problems in the past (except there is always something to fix).

Problem:
On warm days (75 and above) after about a 15 min drive (or longer and sometimes shorter) the car will not start until it has rested appox 22.5 mins (on Tuesdays it is more like 27.5 mins) preferably with its hood open. This has been going on all summer and is driving me batty. I have learned to add an additional 20+ mins to each of my sales calls ... non chargeable.

I became impatient with it one day in August and turned the garden hose on the engine .... and it started right up .... just can not take a hose with me around town.

It runs fine when it runs, and I hope to own it for another 168k miles.

SO .... do you have any ideas, any BTDTs. 

TIA
Rick in DC
