1. Wiring harness issues. Fixed
2. Vacuum hoses all hoses connected.
3. Injector stuck open. Replaced.
4. Current problem I cannot resolve.
Engine surges at 2,500 rpm. Idles perfect. Starts good. Runs smooth up to 2,500 rpm. I am going to replace all injectors with new ones. But have a feeling this is not the problem. I also replaced the distributor. Not the problem either. Everything is new on this engine inside and out. With the exception of some sensors. Cannot drive to a garage for diagnosis so I need help diagnosing from home. I do not own a diagnostic tool and cannot find one that fits this truck. 1997 Nissan pickup hard body XE standard shift VIN 1N6SD11S3VC335887. 2.4L.
Manufactured 11/97.16 pin diagnosis input. Housing located next to hood latch handle under dash. Replaced spark plugs. And after start up run for five minutes plugs are completely black with smutt. Like an old fashioned smudge pot. I am assuming this is from gas as the engine is running very rich. That is it. If anyone can come up with any suggestions that will shed some light on my problem please do. It has been a year it has taken me to rebuild this truck and it runs so smooth and quiet until it hits 2,500 rpm then it runs horrible. I know one of you guys have encountered this problem before. So please if you read this post. Help, JC
