Hi
I've just changed the plugs on my series 2 R33 rb25det, and even though I'm not mechanically great it wasn't that hard, as I took my time and worked my way through it.
I also coated the coil packs with high temp silicone, after readig some posts.
Went with NGK BPR7ES-11 after reading some posts on here.
Cleaned the air filter as well. It has seemed to make a huge difference, the miss I was getting on boost has completely gone, and the car seems to have more power quicker.
The only problem is it is stalling sometimes as I decelerate, The car starts and idles fine at about 600 rpm, goes really well, just has this intermittent stalling issue.
I rechecked all the vacuum hoses, is it something i may have done, or is it totally unrelated.
Should I look at the AFM or 02 sensor?
Any ideas or thoughts appreciated.
