ME hotstart issue

i have an 87 t2 with s5 turbo all emmissions removed freeflowin muff(blown insulation looks like feathers.)

coldstarting is rarely a problem with my t2 , but recently if it stalls it wont start, for days.i understand that if the vehicle stalls it will flood , she is running very rich, but when i go throught all the deflooding procedures im baffled that it still wont start.the engine is not blown or losing compression all oil and water seals are mint . she gets fuel air and spark but if/when she fires she goes up to about 700rpms and dies.

im not sure what to do with it right now in 2 days it will start up and run fine, but i need this hot start prob to go away. again it only has a hot start prob if i stall it.any suggestions would be awesome thks

have you considered sending your injectors to be cleaned? have you replaced your intake gaskets, and eliminated possible vacuum leaks? most often hot starting issues are related to weak compression. anything in the 95psi or under range is considered weak, but not blown.

Don't bother with octane booster or other snake oil.

87 octane is fine for a stock TII but since your car is modified I'd say to go up a level or two. Either way it won't prevent the car from starting.

Why is the car stalling anyway? It should not stall.

Is it in generally good tune? For example, when was the last time the injectors were serviced?

Who did the emissions removal and did this problem start after it was performed?

You didn't do something silly and remove the BAC/cold start thermowax, did you?

my fuel mixture is rich (prolly due to injectors) but other than that and a high idle(1.2k -1.5k )the car never gives me this much trouble.

Sounds like the car is a bit of a basket case.

Factory idle is 750 RPM +- 50 RPM. Put a BAC back on the car and you should be able to set that idle once you fix the vacuum leaks.

Have the injectors professionally serviced (just check the yellow pages for a local shop). Perform a full tuneup and replace the plugs, wires, filters, etc. etc. Also check the CLT and IAT per the FSM instructions. Adjust the TPS. Set the idle to a reasonable level.
