she does not like the one bar loop!!!

hi guys
finally my pulsar is done drove her for the first time last night in months
and she did not like the one bar loop at all .. she was over fueling bad did not like boosting up holding back popping and banging ..
i put the car back to standard last night and she came to life ..
i check how to do the one bar loop again to make sure i done it rite the first time .
has anyone had this problem before ?
cheers len

mine has started stuttering abit when i put my foot down but doesnt do it too often and im puttin it down to crappy fuel

i have been using v-power to run her on . i am going to fit in a boost controller and see if she still does it ..

Not good mate, least you got it back on the road.

Hi buddy ive been running the 1 bar loop for a month now although i did it and mines running 15.6 psi the only time I had any hesitation or backfiring is when my 044 fuel pump was dieing I put in a new pump and shes solid

Have you got a walbro fitted? or maybe do the direct power feed from battery mod, as the old wirig loom is getting past its sellbye date on these cars now! & the standard loom on some cars dousnt put enough voltage to the fuel pump on some R's

i have got a walbro fuel pump that i have not fitted yet but i am going to put it in today .. i will check the voltage on the fuel pump and do the direct power feed .. last night i took her out again and now i have got my missfire back again

what plugs have you got fitted inc gap size ? ignition sytem leads etc ok ? or do you think its fuel related ?

my plugs are NGK iridium only just fitted them gap size i think i did them at 0.7 or 5
my leads are magnecor ..
it mite be fuel related not sure tho just trying everything ...

Get rid of the irridium plugs mate use ngk bcr 8es only a couple of quid each and 1000 times better than the irridium which i paid 70 quid for. Many others have had same problems inc fouling plugs after a couple of start ups or a few runs The tips snap off the irridium. I first read this and did not belive it as many cars i know inc big power use irridium but the pulsar dose not like them

Johnny mate I am trying to find those plugs you have reccomended but can't? Could you link me mate?
Oh by the way Lenzo please let us know what cures your problem, hope it heals soon
