Any help would be appreciated. This is my son's car and he is taking over working thru the problems. He has an FSM & Haynes but not a lot of auto experience.
Symptoms are that when cold, the engine hesitates / stumbles when taking off from a dead stop. Get above a certain RPM and it seems OK. When warmed up it seems to run OK -- occasionally it will die when coming to a stop (push in clutch, let of gas and coast to a stop -- it has died a few times like this).
What has been done is the following.
Replace CHTS (verified working per FSM).
Replace plugs
Clean / flow test injectors, replace one bad.
Splice in new injector connectors.
Replace plugs
Replace dizzy cap / rotor
Verified O2 sensor (mechanic did but son is going to check LED).
He is going to clean / verify the ECU connections and start working thru the FSM diagnostics. Does anyone have other suggestions? Thanks for any help you can provide.
