I got two codes my 95 gsr is throwing....The swap is in a 93 civic ex
It only throws these codes when i accelerate hard and Vtec pops
First code is 22 Which is Vtec pressure switch...What could the problem with my pressure switch be?...because vtec still engages but it engages a little late (6k) and the ecu is a stock ecu

2nd code is code 43 which is Fuel System Supply
What do i need to check here?
The car seems to run rich :S
Any help would be appreciated guys... Thanks

 

Replace Vtec pressure switch, sounds like it is going bad.

For code 43 replace fuel filter and check fuel pressure.

For the rich A/F ratio, check the ECT sensor, more so if cold starting is easy but so easy when engine at running temp. 94
