Hi, I been reading for weeks, done and changed everything I have read that goes wrong with our cars. Still no fix

Car dies: 1st stutters and hesitates while coming to a stop, 2nd give it gas while rolling car goes no where must ease into accelerator, 3rd if I leave the car in drive coast down the road when I get back on the accelerator car dies.
Parts Replaced so far:
1. Main Relay
2. Distributor, includes ignitor, cap, rotor
3. Spark Plugs, Wires.
4. Injectors.
5. IACV
6. Map Sensor
7. Fuel Pump, Fuel Filter
8. Throttle Body gaskets, Lower gasket, Injector seals, and spacer.
9. Timing Belt, Water Pump.
10. ECU

I have ran out parts to change other then the engine. Can some one please help me!!!


P.S. Notice car dies when down hill when it would be going up hill it just hesitate.

 

Sounds like a fuel problem, also verify that the timing belt is not off a tooth.

 

I checked the theeth on timing gear everything is in place and aligned. How do I go about checking fuel if I already replace the injectors and pump.

 

car an automatic?

 

Sounds like the lockup solenoid. What you should do is remove the solenoid, use some deep creep or liquid wrench and spray it into the solenoid. Use a small drill bit and insert it into the solenoid hole and push it in, then spray some penetrating oil in, and work the bit inside and get the solenoid freed up. Then clean it up with some brake cleaner. Apply a thin layer of silicone around the perimeter of the solenoid (as the rubber filter and gasket are NLA) and bolt it back down. Check your fluid level and the colour of the fluid. It should be bright red. If not, drain it and refill with good quality Dextron III atf.

 

I clean the solenoid and changed fluid the doesn't want to start anymore. What should I do now?
