    Holden 6lt l76 problems

    Hey all, recently bought myself a wl statesman 2006 with the 6lt l76 and ever since its been a pig.

    No power no acceleration at all, struggle to climb to 60 wont change into gear withkut backing off from WOt

    I would say maf but its been mafless tuned and has a ramair intake

    Has anyonr experienced similar with this engine and what was the fix...
    Hoping this isn't the time and someone has come up across this before as i need it fixed to get it rwc and in my name


    Only thing i noticed is the ltft in bank 1 are up around -15 where ltft on bank 2 is about -1.5 to -2

    Really hoping it doesnt need a dod delete done already

    Car was left with a dead battery for 6 months or so could the ecu have lost the tune?

    Cheers

    The ECU can't have lost its tune no. Was it running OK before the dead battery for 6 months?

    How's the fuel situation? Stale/water etc

    Someone once asked me if they could use my mower. I said "sure, so long as it doesn't leave my yard"

    O2 sensors. If one is slow to heat up or dead, ecu has a hissy fit. Dumps in fuel and run like shit. Sometimes the connectors also get shirty with loom extensions for long tube headers

    VEs can be pains in the arse. Our old clubby battery went flat a couple of times and played up a bit when restarted, a good Italian tune and letting it sit with aircon on helped if I wasn’t near a laptop.

    As balls said the o2s play games, also give the maf a clean that may assist also. Look for any pcv leaks too.

    You'll know when it's DOD delete time, it'll drop a cylinder at best or not run at worst.

    Whats the fuel pressure like? Never been a fan of letting fuel sit in things for extended periods of time.

    Are these flexfuel? E85 sitting around wouldn't be good.

    So got some time to spend on this thing over the weekend, looks like it's dropped compression on the LHS bank so heads off but no noticeable damage, will check for metal fragments soon.

    I am thinking it has collapsed the cat on that bank possibly through bad 02's dumping excess fuel or something. if no chunks of metal are in the oil, going to throw a set of head gaskets and bolts and it button it back up hit the key with the exhaust off and see what happens.

    If not, has anyone got a good lead on a reasonably price L98? or a DOD deleted L76/L77

    Cheers

    If you do a DOD delete you need to do a cam at the same time, and a re-tune. If you just want it going again you can just replace the DOD lifters, they aren't that expensive.

    An L77 is basically an l98 with the DOD shit. In my humble opinion find yourself an LS2 cam and lifters, that will liven it up enough to not take away the standard feel of it.

    Or go to town and plonk a stick in it that will wake the neighbourhood
