Weird boost/fuel cut at 0.7 BAR - EVO 4
]am getting a weird boost cut (I think) when I hit around .7 bar. I lose acceleration and start to back fire if I hold the gas pedal down.
I went to a local mechanic and we checked for boost/vacuum leaks and couldn't find anything. Also took a look at the plugs and he saw signs that my car is probably running lean (in his opinion)He recommended a new tps and boost sensor.
Troubleshooting done so far:
-Changed plugs gapped to .026
-Checked battery and alternator
-Set tps to .07V at idle/ played around with different tps settings
-Ordered a new tps that will arrive soon
Next we did some logging on evo scan.
These are 3rd gear pulls at WOT. Boost builds cleanly then cuts out at .7 BAR
I am at a complete loss here, any help would be appreciated
