Hopefully this will sound familiar to someone!
My 14 SR is running very rough, basically it's fine if I drive around town (except for the blown exhaust manifold..) however, when I get to around 60-70 (on the novas clocks) - 4th-5th gear it begins to misfire like hell and pops and flames, seems like over fuelling to me?
It can get really bad, to the extent that the car just wants to cut out, and I have to let it, or stall it myself etc dropping down gears doens't seem to rectify the problem either.
However once I've been able to pull away from standstill and providing I dont go over say 45-50 mph (4h gear max) It is fine.
This is really confusing to me because it seems to be down to air/fuel issues, but surely this would happen regardless of the gear its in?
So far I have changed the plugs/leads and added a new K&N panel filter (had it lying around)
I don't recall if it had these symptoms before, but I have removed the EGR thing that bolts to the exhaust manifold and joins to the air intake..
Been told maybe it could be the spark enhancer or something?
Gave as much info as possible here, oh yeah and it's **** on fuel!
Any help appreciated, thanks NL'ers, Liam
