R31 Problems

[shawnie]

hey guys, just joined to this site to get some ideas. I have 1990 R31 auto sedan that im having some major issues with. It was missing coughing and spluttering. Took it to shop they replaced the air flow metre, the fuel pressure regulator and adjusted the timing, now it doesnt miss but still the odd back fire when you put your foot into it. Its also really really sluggish, like no power at all from a standing start. It does have a leaking manifold/exhaust gasket but surely that cant be whats making it lose so much power. Any ideas guys? Thanks!.

I installed a program at work yesterday (Auto Tech Encyclopedia - from Repco), and there was a section on 'Problems' since I've got a Datsun I though I would see what was in there for my car, but there was nothing in there for my car, but it did have a R31, this it what it said. sounds like your issue.

Hi,

You can also check the R31 forum. http://forum.r31skylineclub.com/index.php 

Lots of detailed info there, for example:

Sounds like the CAS to me

Car would run fine then sudden loss of power.

Are there any error codes coming up on the computer?

That's some good info there JH

Seems like we all suspect the same thing.

Sounds like the shop were guessing unless there were no error codes

Check your inlet manifold with a can of oil if it sucks it in when engine is on could cause it to use heaps of fuel and be underpowered.

Change inlet manifold gasket if it's leaking ie sucking oil in.

The cat could be blocked or broken/rattly,do a comp test could be burnt valves or cracked head at worst.
