Problems after oil Change


DarkForce

Recommended Posts

Having some severe issues with my 2005 350GT (identical to the 350z VQ35DE) happened straight after an oil change(I purchased the same oil/filter as last 10 services) had a CEL and a p0021 error, car in limp mode, change the front VVT solenoid and a cam sensor(B2). Car is running really rich (17MPG) every since and struggles/sluggish. Cleaned the throttle body and changes the air filter, and did an idle relearn and no change, it came up with a P0340 cam sensor fault/CEL a week later..changed the cam 1 sensor and the car struggled to start(long crank, poss dodgy sensor(....not sure it was a bad oil change that caused the original fault or someone worse (timing chain?)

 

 Don't want to end up with work/replacing parts without fixing the issue.... hope someone can help!

I've changed the cam sensor to an OEM one, however on reading the codes these came up, This is straight after a p0021 error and replacing the VVT intake solenoid (it was clean and not gunked/siezed)

C1109-Battery Voltage Out of |Range
C1130- Engine 1 Fuel Cut System Fault


This seems like a whole separate issues, is the non-oem sensor likely to cause these? I was reading up online and the alternator can be the cause, I have a new battery (Optima yellow top) and I have been hearing a squealing sound on starting the car esp when it's cold (high pitch, goes away after about 1 minute) read the voltage is around 13.5 car off and around 14.5 with everyone on (ac, lights etc..)

Car is really sluggish and not managed to maintain rps, esp at low range, it's bouncing, idle drops to around 650.
Going to recheck all the grounds again, 

Really at my wits end...
