So here goes:
I braught a gtir a couple of months ago and it always had this problem, it accelerates erraticly, eg: it comes on power than loses it then gains it again and so on.
At first I thaught "water in the dizzy" because probably the Moran washed the engine with a pressure washer from the top... Anyway I checked the dizzy and the seal is missing about 1cm on the bottom of it and with that massive scoop the gtir has and no top mouth intercooler ( got a front mount) humidity would seep in over night and a lot of corrosion would accour on the pins, so much that I had to scrape them every 1-2 weeks but every time I did this the car felt better but still had this hesitation on acceleration, also checked the spark plugs(after buying the car) and they had water on top, so I cleaned that and water hasn't reappeared, after this I checked for boost leaks with a conpressor going from after the first pipe of the intercooler bolted to the turbo and plugged just before the inletmanifold. Pressuruzed to 2 bar and nothing, I wasn't happy so I kept looking and hey Presto I found some horrible things, first immage is the big 2,5 cm diameter rubber tube that comes out the bottom of the manifold about 5 cm after the intercooler piping ends (where is this capped piping suppose to be plummed to?)
Then I took the intercooler piping off the turbo and what a supprise another seal missing a cm... I repleced that..
Then checkedt the piping from the turbo to the air filter. And here I have to say I am so appauld... Sikaflex stuck in 2 side holes.. (what if it dislodged and went in the turbo? I can't believe this...)
Anyway I plugged those holes and tested it and the car seemed to go much much better but it still has this hesitation!!! And it's getting worse to the point I can no longer drive it now,
Yesterday I checked injectors as there is a ticking sound coming from the engine and the first injector (where the ticking sound is coming from) signed 0 ohms and all others say 2 ohms the injectors are Jecs A46-00 yellow top which by jecs specification should be 11.2 so I checked them again and now all 4 are reading 2 ohms? So now I am like wtf...
I know that gtirs have low impendence incjectors but to be sure could someone checked their injectors?
I'm going to check the fuel pump this weekend,
Soory for te long post guys I didn't mean too but there is so much stuff I need to understand
Thanks in advance guys!
