Lawless Posted March 1, 2012 Share Posted March 1, 2012 Recently had a low mileage engine fitted from gt bitz engine had 37000 miles on it but since doing the engine swap the car hasnt been running rite it seems to be a bit juddery at low revs and is really hesitant to boost in low boost it's not rely noticeable and runs ok but when I change to high boost it seems like the boost is there but the engines not allowing it I really have no idea what this could be ?

Lawless Posted March 1, 2012 Author Share Posted March 1, 2012 Also had oil light faintly flickering after fitting a dump valve but removed this and put standard one on appeared to cure the problem Quote Link to post Share on other sites
H_D Posted March 1, 2012 Share Posted March 1, 2012 Do a compression test and check for boost leaks.There was a thread put up on tggt about GT bitz and the issues alot of people have had with them regarding faulty parts and disputes Quote Link to post Share on other sites
Lawless Posted March 1, 2012 Author Share Posted March 1, 2012 Really ok will get it looked at the engine seemed mint and I think is still under a warranty of 3 months or somthing it's just really worrying when you fork out for this job and it's not right Quote Link to post Share on other sites
Lawless Posted March 9, 2012 Author Share Posted March 9, 2012 Had the car looked over they changed the oil pressure sensor because the oil light was flickering from time to time and apparently the bogging and the car boosting in spurts on high boost was to do with the ignition timing this sorted the problem have had it back 2 days and it's gone back to how it was before they worked on it confused Quote Link to post Share on other sites
Taggy Posted March 9, 2012 Share Posted March 9, 2012 Take it back to the garage, did GTBitz fit it? Quote Link to post Share on other sites
Lawless Posted March 10, 2012 Author Share Posted March 10, 2012 No my local garage fitted it I have all the receipts and everything still I've not tampered with it in anyway and it's my daily it worked fine for a day now it's missfiring all over the place again could it just be down to timing because the engine is really strong apparently Quote Link to post Share on other sites
Lawless Posted March 11, 2012 Author Share Posted March 11, 2012 Have had new leads again new sparks dizzy cap and cleaned all sensors and idle control valve but still misfiring starting to wonder if I've bought a dodgy engine Quote Link to post Share on other sites
Lawless Posted March 13, 2012 Author Share Posted March 13, 2012 Finally sorted it turns out to be ignition timing wasn't rite and a faulty set of spark plugs but now running sweeeet Quote Link to post Share on other sites
