Here it goes. I have a 96 zetek sport, 5 speed, with 75K on it. My CEL came on about a month ago, got the code pulled and it comes up as a P0171. The symptoms seem to be a hunting/rhythmic idle. It is most noticeable the first time I start the car each day, and lately it has stalled out a few times. After a bit when the engine gets warm it calms down for the most part but idles a little above 1K. Another problem with the car that only adds to this, and has been a problem since I got the car, that occurs approximatley between 1500 and 2000 RPM's. When pushing on the gas just a hair to get it in this range, the idle starts to jump considerably, but never stalls out. It shoots down to like 500 then back and repeats itself until I give it more gas and climb above 2K. Everything above that is fine, but this is a real pain.
Before I start to buy parts I could use some of your collective wisdom. I changed out the PCV valve before the CEL came on, I cant remember how long before it was however, I would say less then a month. Not sure if this would have any effect. I am heading home from school this weekend and going to attempt to find whats going wrong. I worked on a golf course back home over the summer and can use the shop they have there. They got a lift and every tool you could want, so its a good perk.
Thanks in advance for any help, I really appreciate it.
