I am about to inherit a 2001 Colorado. it's the 3l intercooled common rail diesel.
It was my late dad's car, he bought it new and my mum has driven it since he died 7 years ago.
It's been a damned good car, very few issues. Rusty rear lights, drivers seat collapsed years ago and the passenger door mirror does odd things in the rain were about it. Until recently....
Ever since a tank of Tesco diesel it has occasionally had a hiccup. Starts no problem and revs freely off load. On load can be a different story.
It'll pull away then sometimes around 2500 rpm just runs out of steam. Hold your foot on the floor and it will maintain speed but not accelerate, and occasionally surge and take off like a scalded cat.
The engine management warning light has been on and off.
it has the odd day where it's perfect, but this has become more prevalent now so my mum has ordered a Rav4 to replace it, and passed the LC on to me.
Thus far it's had fuel biocide treatment (don't think that made any odds), fuel injection cleaner (this made some improvement), fuel filter replaced with genuine item (the EM light has not been on since) and also a spray of 10K boost EGR cleaner (again this made some improvement).
Next on the list to look at are the pick up from the tank (is there a pump in the tank?), and the fuel lines themselves.
I've read a lot on the interweb about suction control valves, so I'll give those a clean and replace turned through 180 degrees.
