Re: Weid MAP issue

New swap? MAP and TPS plugs switched?

Re: Weid MAP issue

No, Sir this swap has like 4 years.

Map and TPS plugs are fine.

This start like a TPS issue, bogging a little at take off, and getting worse to the point that now only stay at idle and sputter and die when press the gas.

NO CEL.

Apart from the fuel system: Pump, filter and regulator (all new) and Distributor (45k from ITR swap). what can cause this type of failure?

New, TPS and MAP.
