I have been chasing issues with this motor since I bought the car. It is backfiring and won’t accelerate with power. 43 lbs of fuel pressure is what it has. It back pops when idling ever so often. You try to rev it and it like counts to 3 before the rpms try to come up. It’s giving a cam position sensor and crank sensor code. I put a new cam sensor in and it didn’t even get rid of the code. Can the crank sensor cause this ? Thanks
