Over the weekend I change the UIM and LIM and noticed that the PCV did not have a spring
I got a 98 Bonneville, non SC with 155000K. Had issues with this engine since purchasing it in 2001. Thanks to this forum I was able to put to rest my engine issues from the past (UIM - Coolant leak). But know my engine is running slughish.
here are some syptoms:
1. At Idle, it revs to below 1000rpm. throttle up to 2500 and it sounds like gasping for air and when it settle back to idle it sometime backfires. This only happens when the A/C switch on.
2. When i turn off the a/c, It idles around 1100 and still sluggish but a little better. I am know hearing a hissing sound.
3. During driving conditions - when accel the car is hesitating and need to rev it up to 3000-4000rpm until this hesitation stops.
4. upon starting the car it takes time to crank the engine over and then their is (i believe) blue smoke.
I have spent allot of time and monies to get the engine back prior to the 2001 issues.
I reading all the threads its point to the PCV or EGR. So any help is appreciated.
