i sold it for 5k last sept so something must have happened it. i got a full respray done and it was mint when it left my yard. the lad who had it after made a mess of the interior. still was a very good car but couldnt afford to tax it anymore so got rid of it.

worse case would be like mine and its dett. mine happened when engine hits boost and as is said sounds like marbles in a jam jar. Hope its only something small for your sake as i took me 4 months to sort my rattle out.

After Many months of changing this and fixing that i may have found my solution to the dett problem. So far i have changed both o2 sensors coil packs cleaned all injector connection and then replaced cas unit as my timing kept slipping. re aligned my cam belt 3 times as i kept thinking it slipped a tooth. More recently changed my Fuel pump (thanks to Phile). So this morning i took off my aac and replaced it. connection on it were loose which caused my revs to go up to 2000 rpm. sorted that and replaced a fuel pipe beside the fpr. Jumped in as i have done 100s of time before not holdin out much hope but on the hill up to the house i planted the foot and hey presto no marbles in jam jar. i still expect it come back but as the weather is fine might throw the targas in the boot and go for a long drive and enjoy the sun.

ill be in croke pk watching tipp beat Killkenny while my Z is sittin my garage with the front of the engine stripped down. Belt slipped a tooth or 4 again so think of washing my hands of Z and buying a Mini. Enjoy tommorow.

sorry i cant make it. fuel pump has gone and cant afford a new one. would love to be there again but funds are low. have a great day though. hope ye get the weather like last year.

yea i thought that too. cant understand it. i have checked the resistance of each injector and it read 13.2 on all of them so i think they are fine. but the scan keeps saying o% on duty cycle. ??????????????????????????????

When i do a scan the duty cycle show as 0 at idle and on rev. as i am not too up to date with the data scan as yet can anyone shed some light on this. and also can this cause my dett problem (yes still got the bloody dett problem) Thanks

Iv tried everything else to cure my dett problem and was just thinking that my fuel pump might be the cause. its very noisey most of the time and may be causing it to run lean. might be way wrong but i am running out if ideas now. Already changed O2 sensors, checked timing belt and Adjusted Tps to 40 and fixed timing to 15 degrees. Oh also tried another ECU just to be sure. Put in a Octane boost as fuel here is crap. but might not have been a good brand. Have i missed something.

sorry to hear about your mom Trish. Hope she gets better soon. My car is been handed into a place called predator motorsport today and i dont want it back till its done. i hate having to pay for problem that i can sort myself but this has me baffled.

slowly or fast really makes no differance but you can hear the rattle more when you get boost. get it checked by jeff in zedworld to be on the safe side.

bad news again lads. rattle is back. noticed it yeasterday morning and got really pissed off with it. so i striped down the cambelt to make sure it was on rite. seems it may have also slipped a tooth so put it on correct double checked it and then checked again. put it all back together re timed it to 15 degrees making sure my tps was at 40 and took it for a run. rattle still there. ( think its laughing at me now). so today i put some spare O2 sensors on it and its still the same. so i am gonna have to bite the bullit and give it to a specialist tommorow. i hate getting beat by something but i just cant fix this one.

slight misfire cause of the 5 degrees timing but its better than the rattle. will let a specialist look at it tomorrow anyway. Thanks for all your help lads its much appreciated.

ok looks like i have victory. where do i start. ok i added a can of pro boost as i was told by jamie that the octane level might cause. so after doing that with no real improvment i decided to proper check the timing again. this is where the fun started. attached all my leads and lamp and to my amazement my timing was set at 35 degrees BTDC. my jaw dropped. so i set it back to 15 and the rattle decreased quiet a bit but not gane. so i rang a mecanic friend who said that pre ignition is a common problem and suggested that i drop it to between 5 and 10 and see if it makes a differance, which i did and away she went flying. i also noticed that my ECU has a series 1 chip so dropping the timing i was told is the thing to do. i dunno but it worked.

trying to get a hold on jeff but the phone number on the website turns out to be a fax number (getting the fax sound). does anybody know the number.

once the other members dont mind as i would love to meet up with everyone but the way my car is could be a while. bringing it to a specialist tomorrow to see if he can shed some light on the problem but doesnt look too good im afraid.

For some reason i cant add the log. All i can say is one o2 sensor is reading at 27 even when i rev the engine is only moves up a little where as the o2 sensor rh is at 57 and moves between 14 and 60 when rev'd. Does this mean anything. The af ratio still says lean. Engine was at normal operating temp.

No idea about the bar bluenik but thanks for the imput. every little helps. ok i decided to have a go at it tonight so took off the balance bar whick to my surprise was very loose on one side (might have been sucking in air there). cleaned all the connections including injectors whick were all green with corrosion and a pipe whick was held together with duck tape. so then i put everythink back together again making sure everything was tight and clean. took her for a spin and even though she is driving better (great actually) the fooking rattle is still there. i then done my data scan again and logged the data which i will post in a few mins for anyone who understands that stuff. no faults were shown though. THANKS TO EVERYONE FOR POSTING THOUGH. THIS REALLY IS A GREAT PLACE AND SOME FANTASTIC PEOPLE IN HERE.

yea thats the readings i get. trying to post the reading i got as soon as my laptop behaves itself and installs flash player. its all going wrong.

im not gonna make it now either. look on the help and advice section under (wits end). i am have serious problems. cars gonna be off the road for a while i think. engine is nearly fooked. dettin or something.

i used a clamp on the no. 1 plug and powers from battery. also set the tps to .40 but that seem to have sliped to .38 now. will reset it.

where did you get the software your running. is it expensive and hard to get.

i have no upgrade or boost jets. she is very basic i believe. stainless steel exhaust and induction kit is all i think. stenort what picture is that. look more useful than mine.

no mine show dials (clocks) its nissan data scan v1.52.

a/f base at idle reads 109 (engine warm) af base SL RH READS 100. o2 SENSOR b1 READS 0. O2 sensor B2 reads 0. i have been trying to understand what these reading mean by not getting any sleep last night but i think i will leave it to the pros. Timimg is set at 15 degrees which i set myself after i changed my belt. i used a timing light from crank. believe it or not i have a fully operational garage with 1000s euro worth of tool. but cant fix when i dont know whats wrong. this car is my life and if it dies after all the money iv put into it my missus will kill me along with it.

put it on conzult again during the night and the a/f ratio says leans one minute and rich the next. i took pics of the conzult reading and will try to put them up as soon as i can.
