So, have had slight issues with my ´04 TD5 Defender, 200.000km.
From a cold start it absolutely sucks at torq and I have to A) wait for the engine to warm up 5mins or B) use 4low to get out of my driveways small hill. Engine starts fine, on the first try. Engine runs evenly and does not have any extra noises. It even revs normally when on neutral.
But, in gear and trying to get up that small (15%?) hill and it just start choking, stuttering and dies.
History:
- Blew the head gasket in jan & shop repaired it. It did not seem that engine suffered any extra damage.
Gaskets have gone before as previous owner had installed the new AMC cover, but the previous owner failed to install it properly and it failed on me.
- Injector nr 3 was changed few months after gasket job.
- All the filters have been changed.
- Fuel Pressure Regulator has been changed.
- Throttle pedal crapped out few months ago and was changed.
- Eyeballed MAP & MAF sensors and they looked ok.
- Wiring loom on the engine side has been chaged.
- Turbo wastegate was sticky and caused one overboost but now seems to move quite freely.
- Turbo hose had a small oil leak but repaired, the shop said the turbo was ok though.
When warm & highway engine performs relatively well. Pulls ok´ish on higher revs, can hold 120-130kmp/h but lacks the low range torque, imo.
So, any guesses where to start to hunt for poor performance? Will get a nanocom in the couple of weeks, but could start troubleshooting in the meantime..
Thx in advance!!
