M100 - Error 34 - Elan scan faults 800

[martinpt]

Hello , i'm a newest buyer of Lotus Elan M100.
So I started driving the car without any problems then I blow the radiator house because of the pressure in the coolant circuit, I went to the mechanic and he found a problem with the head gasket.
He has replace the head gasket, oil seals and valves, after that i drove the car without any problems but somehow the car started to switch on the engine light and can't drove above 2500RPM and the car makes a lot of smoke.
after many times to throttle at max the error disappears and the car runs well until the next light on...
I made ALDL test and give me the error 34, after that I bought FTI interface to make the test under Elan Scan and appears faults 800 with the map low ON.

Any good soul can help me with this problem?

Code 34 is consistent with fault code 800: The Mass Air Pressure (MAP) reading is low. The ElanScan air pressures look sensible so you might have an intermittent problem on the wiring - I'd check the connector to the MAP. There is some information about the MAP on the WikiLEC.
