Trouble Code 33 and 34 are the MAF/MAP Sensor
Circuit. It sounds like you've replaced that sensor already. Did you also have the code 34 before putting in the new sensor?
Or did this code start after it's replacement? Any other codes appearing?
Troubleshooting it would depend if it has the Speed Density
Update. The dealer should be able to provide that info.
Here's your fault code list:
13
oxygen sensor circuit
14
coolant temp sensor circuit (high temp)
15
coolant temp sensor circuit (low temp)
21
throttle position sensor (TPS) circuit (high signal)
22
throttle position sensor (TPS) circuit (low signal)
23
manifold air temp (MAT) circuit (low temp)
24
vehicle speed sensor (VSS) circuit
25
manifold air temp (MAT) circuit (high signal)
31
wastegate solenoid electrical circuit
32
exhaust gas recirculation (EGR) circuit
33
mass air flow (MAF) circuit (gm/sec high)
34
mass air flow (MAF) circuit (gm/sec low)
41
cam sensor circuit
42
C3I EST or bypass circuit failure
43
electronic spark control (ESC) circuit
44
oxygen sensor circuit (lean exhaust)
45
oxygen sensor circuit (rich exhaust)
51
PROM error
52
calpak error
55
ECM error

be sure the cig lighter is working, if it does not work the scanner will not work and be sure the C.E.L. works. if not check the bulb

what is the year mahe and model of your jumpy jerkey car? is it throttle body injection carborated ot electronic fuel injection ?have you taken the fuel rail or line loose and tried blowing it out with a strong blast of compressed air ??if you changed the fuel filter and it was dirty and you say you changed the tank and fuel pump you more than likely
are experiancing what they often refer to as butterfly action in your fuel line or your injectors are plugging up sounds to me more like a piece of rust or something of that nature doing a little gate or butterfly trick on you .. a single piece of rust can cause trouble for years if it is big enough and in the right position in the fuel line.. take your fuel line loose at the tank, both ends of the filter and the injector rail and with a strong compressor blow backwards through the fuel line,both from the engine to the filter end and from the other filter end to the tank (caution ) ( caution ) do not i say do not blow compressed air backwards through the fuel pump you will blow a hole in the diaphram and ruin the pump adding to the expense or your repairs dramaticly..
if that dont do the trick my next suggestion would be get the code connector fixed and get a good reading on the computer ..one more thing how good are you with elictrical ? it could be a short in the ignition switch or wires going to it keep me posted we will try to get it sorted out for you good luck and i hope this helps
