hi folks,
got a new problem with the car i haven't encountered before.. as a background.. my battery ran flat last week so after getting it recharged at the shop few days later.. i think i can hear det on light load.. i have a wideband wired in and on idle it used to be 14 odd now its constantly low 13 afr.. also when accelerating smoothly i can see my afr dipping into low 12 sometimes 11 on the afr gauge..
my suspect is the fuel pump failing due to the perhaps too much draw placed on it while i was using a semi charged battery.. could perhaps be the FPR, fuel filter or bad earth.. in either case.. im looking at changing the fuel filter and putting fuel pressure gauge in to check pressure this arvo
currently i have a sard fuel pump in there.. no odd noises.. primes fine.. no hesistation from the car.. i do have pretty bad fuel economy of late and car doesn't feel as nippy as it used to.. i have read past thread on dying fuel pump but would like to hear if i have missed anything out, will look at getting it on a dyno for a run but that could take a week
