Car Trouble Bnr32 1990
Attached is the Nistune Log fresh this morning along with the items that the dealer have changed. My Car studder and shivers between 1k-2k rpm no matter what gear it is. The problem partially went away after they changed the items like gasket , maf,o2 sensor, and seals. But it still happens and I cant pinpoint the problem, last time the car was serviced it took them two weeks before getting my car back. It is my daily and I cant really afford that long down time >_< . This just happens in that rpm range >_< usually happens when the car is cold and even when the operating temp is reach it still happens , but not as much.

Cannot really see much without you including the wideband data in the log or tune file
I'm just seeing about 2-2.5ms injection time around the low area but nothing which shows a problem yet

Re: Car Trouble Bnr32 1990
I dont have a wb hooked up, and it is the stock tune from the nistune board. Im just trying to figure out what is causing it , because even the chipped tune ecu i have this problem is happening. the wb is on the way from 14point
Re: Car Trouble Bnr32 1990
Sorry not something I can diagnose without being at the car and checking
- AFR mixtures
- Leaks
- MAF
- Fuel pressure
etc

Don't know 100% for RB but if it would be SR I'll try know good CAS ... they usually give some "stupid" errors
Re: Car Trouble Bnr32 1990
Nothing in that log will tell us what is wrong with the vehicle. It seems to look fine from the usual critical sensor inputs (RPM, MAF and temperature)
Re: Car Trouble Bnr32 1990
Check for a vacuum leak. Use carb cleaner or the like. Spray around the injectors and TB at idle. Listen for a rise in RPM.
Otherwise the stock MAF can be finicky.
