Hi, changed plugs to ngk iridium ix. Now having boost problems. Yes i took several pipes off but have undone them all and re tightened them. If it's a leak shouldnt the turbo still spin up properly just will have lack of boost? Mine is very sluggish and only gets to between 5and 10 psi (should be 13). car still runs abit rough at idle too which is why i changed plugs. Theres a componant in centre top of motor which has two pipes going to it and wires to the boost sensor. what is this? mine is looking corroded. Boost seemed fine before plug change. \

Thanks Brent

Hi, I thought that may have been the case as i was finishing job in dark and unsure of two of the coils! Just reversed them, no good. After replacing plugs i drove to shops - around 1km. downhill and cold motor so i just cruised. No problems at all. then on way back throttled it expecting to hear that loverly turbo sound but only went to 10psi. Still ran ok though without boost. after a couple more runs it's getting worse. Boost very erratic. just had it going uphill on quarter throttle, 2or 3 psi and it's missing badly. took three plugs out and they are badly carboned up. this is after maybe 4km total running. could it be the AFM? I did have all the pipes off it overnight.

Sounds like an intake leak somewhere. I would be focusing on things you touched before there was a change in behavior. Rig up an attachment so that you can pressurise the intake and see if it drops pressure, then you can track down the leak.

      I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 馃ぃ, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up

      Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.

      We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
