I replaced my TPS, ISC and EGR Valve, now my car will start and stalls immediately.

Every time? It will not idle at all?

I`m curious about this also..
the other day, I started my 1990, which as always fired up emediatly, but then, it also emediatly stalled..so I hit the key again,...same thing..this happen a few times, so I just left it alone for a little while..came back, hit the key, it fired up emediatly, but then instantly stalled again..tried it one more time..but this time, it kept running...
drove it a few places after that, and no problems..
No codes either???

Did you adjust the ISC motor when you installed it?

Was just thumbing through my manual and ran across this..

"engine starts but stops emediatly"
1. loose or faulty electrical connection at coil pack or alternator
2. Insufficient fuel reaching the fuel injectors
3. Vacum leak at the gasket between the intake manifold/plenum and throttle body
4. restricted exaust system (most likely catalytic convertor)..
