Hello Everybody its been a while since I have posted as life has been pretty hectic and the Nissan has been tucked up in the garage for much too long!
I really would like to get it sorted so looking for advice...
The car ran fine, but was mapped very poorly.
I took it off the road changed the manifold, turbo, downpipe and boot pipes with the intention of getting it mapped once back together
Put it all back together and since then it hasn't run right and I don't want to take it for mapping when there are problems.
It has a very rough idle, it sits at around 2k and drops every so often and misfires
if left to idle till warm the idle eventually drops to 1k but still misfires occasionally
It is running extremely rich
When driving it is okay under light load and off boost
When it is loaded and boost comes in it is like hitting a wall
What I have done so far:
Changed the plugs
Cleaned all electrical connectors
Cleaned AFM
Cleaned ICV
Checked for boost leaks, although I think a pressure test may be better
Any ideas?
