Hey everyone,
So I am having a pretty crazy issue I have been trying to figure out for the past 2 weeks. So, when I start my car it will run fine for the first 3 or so minutes, It boosts fine and feels great! However, all of a sudden my car starts breaking up and will NOT rev past 2k rpms until I shut the car off and restart it.
So what I have done to figure out whats going on. Replaced my plugs with BPr7es NGK plugs, Newer NGK wires about 4k miles on them, Compression test as follows, 152, 150, 154, 154. Timing is dead on marks on the cam gears and crank line up at 5* base. New denso o2 sensor (just replaced yesterday) and boost leak tested at 20psi, Found some leaks but they are all fixed now.
This all started after I replaced my clutch and flywheel (weird). I really thought this issue was my o2 sensor not cycling, So I replaced the o2 and its finally cycling again. But it has not fixed the issue at all. Any insight would be great. My computer wont link up to my logger so I cant post a log as of now.
Mods are as follows
keydiver chipped ecu, 2g maf, Dejon intake, RC 550cc injectors, Rewired Walbro 255, Bastard 20g.
