    Help wth tps (Throttle Position Sensor) problem/ Or just removing Throttle Body

    I need some help, soon if possible.

    I was trying to remove my egr valve to fix code e48, In the process the tps connector broke off. My car now idles very high at first then falls all the way down to stall speed. It set codes

    E22 Open TPS Signal
    E52 (Battery Disconect)
    E71 Intermittent MAP Sensor Signal

    I can not get my TPS off with a offset star wrench, Just wont go, looks as if one screw was already stripped. I think I can fix the connector but would prefer to get it out of the car to do so.

    I tried to remove my throttle body but I do not know how to get some of the lines off. If anyone had tips on how to easily remove the 4.9 throttle body I would appreciate it.

    I took it for a drive and it ran like crap up till 30mph when it had a 2 minute delay to shift gears, once I got around 40 it flew all the way to 60 just like normal.

    If I go into Diag P.0.1 the tps reads -92/ -88 and doesn't adjust when i give it gas.

    I am about ready to just try and solder the connector on the car if I cant figure it out.

    I got it running again, I used some solder too build up the connector, and the tps wires now make contact. It is a crappy fix but the car is driveable till this weekend when I can get a better tool to remove it and fix it properly.

    You always can disconnect ISC motor until you fix TPS. Removing TB is easy just remember all those vacuum hoses to put them back or replace.
