having a problem with 87 t type. had a new fuel pump installed, had trouble with ground. got that straihten out, service engine light came on showed code for erg valve solenoid,. replaced erg valve solenoid. car is running some what cracy.. starts up fine but when shifting for 1 st to 2 nd and from 2 nd to 3 rd it stumbles real pronounced at 30 to 40 miles per hour. just replaced the erg valve now but it stills stumbles. any ideas what to do?:)
