i got a good question for you???
i have totally rebuilt my whole motor and i never hooked back up my factory oil pressure sender would this cause the car to jerk very hard at or around 4500 rpms im using a aem computer now.. when i say jerk i mean pretty violently jerk lmk
i have had one person tell me yes but what i dont understand this isnt the factory computer anymore so how does this computer know that it isnt hooked up thanks

this is the only thing i think that could cause this problem lmk what you think

 

sounds like a clutch problem is the clutch new with a new flywheel,or the flywheel resurfaced?maybe even a fuelPressure problem

 

the clutch is fine its just when your driving its like the motor just doesnt want to go at that point when tuning its does the same thing it doesnt have anything to to with that it something else just cant put my hands on it was just wondering if anyone has had this problem or if they have left out the factory oil pressure sending unit

 

if its obd2 might be O2 sensor

 

really why is that what would cause the o2 to make the car do that but as i asked before do you think that the oil sender could cause this

 

The oil sending unit has nothing to do with the issue you are having.
An aem ems nor stock ecu rely on the oil pressure sending unit.

It sounds like a vacuum leak or tuning issue.

 

thanks but what about the msd going bad im going to go though
everything tomorrow just trying to get maybe a idea t hasn't ran right since the end of the build it runs fine down low but like i said when you get to that point it jerks alot more violent not that the turbo is on and not trying to kill it just daily driving no more than half throttle

 

check your plugs...just a shot

 

not that old bought new ones today and putting those in tomorrow to see what that does im also running a degree cooler 7 ngk platinums these are the new plugs im putting in tomorrow

thanks to everyone that has replied any others suggestions lmk

 

Take the car to a shop that knows what they are doing. Trying to diagnose an issue like this remotely via the internet is pointless.
