tommyep82 Posted April 9, 2015 Share Posted April 9, 2015 Well lads do the mechanical part of the distributors on the 4efte engine give any problems?Was getting car mapped to and had a Splutter past 6700 ish under full load, but if u bring power on easy it will rev out. Any suggestions car is driving and boosting perfect apart from that? Quote Link to post Share on other sites
Gainzy Posted April 9, 2015 Share Posted April 9, 2015 Never heard of any problems from them just buy new dizzy and rotor arm Quote Link to post Share on other sites
tommyep82 Posted April 9, 2015 Author Share Posted April 9, 2015 Dizzy rotar and leads are only about a year old, New plugs, coil is next to try and earths don't know after that head is melted Quote Link to post Share on other sites
Mk3 silver gt Posted April 9, 2015 Share Posted April 9, 2015 My mate is having the same problems and tried my working leads and dizzy cap and rotor today and still the same but didn't think about trying the whole dizzy, but did a compression test and that came back fine? The next thing I was gonna try was the coilpack and ignitor but it's strange! Let me know if you sort it out or if I do il let you know Quote Link to post Share on other sites
tommyep82 Posted April 9, 2015 Author Share Posted April 9, 2015 I will mate it's very odd what is happening like spark is breaking down. I had a meter on my tps today and its 5volts at idle possession then reduces as throttle is open and goes into minus voltage near wot is this normal as I'm having a Splutter at 6800rpm at full load but is ok when I bring it up not under full load Quote Link to post Share on other sites
mikey4410 Posted April 10, 2015 Share Posted April 10, 2015 only time I have had a miss fire is when my coil pack started to fail....and theres no set rpm u will have an issue at,mine happened to be at 2,200 but for others theres an infinite variable of rpm spots with issues.

tommyep82 Posted April 10, 2015 Author Share Posted April 10, 2015 Thanks lads anyone ever see tps sensor couse this problem maybe Quote Link to post Share on other sites
tommyep82 Posted April 12, 2015 Author Share Posted April 12, 2015 Well lads also I can't get the throttle percentage off the laptop when I have it pluged into my emanage ultimate either if this has anything to do with my miss fire or not?? Quote Link to post Share on other sites
daniel_g Posted April 12, 2015 Share Posted April 12, 2015 Could try another TPS ? Although im not sure what the EMU will read as the TPS is basically an on / off switch Well lads also I can't get the throttle percentage off the laptop when I have it pluged into my emanage ultimate either if this has anything to do with my miss fire or not??

tommyep82 Posted April 12, 2015 Author Share Posted April 12, 2015 They are not that handy to change tho mate and fairly sure they are just an on off switch Quote Link to post Share on other sites
morgey Posted April 12, 2015 Share Posted April 12, 2015 Manual tps have 3 postions i think i saw the other day ill see if i can find it Quote Link to post Share on other sites
morgey Posted April 12, 2015 Share Posted April 12, 2015 Your multimeter's lying to you ;) A negative voltage reading basically means you've got the leads the wrong way round when measuring DC. So, the voltage is coming in through the black and out through the red. On your original question, I'd check continuity with your MM diretly into the 3 pins on the TPS. At 0 throttle, you should have continuity from middle to top, from 25% to 75% you should get no continuity and from 75% up you should get middle->bottom. If there's any cross-talk between the pins I'd take the TPS off and crack it open and you should be able to see where the problem is easy enough.From your other post Quote Link to post Share on other sites
tommyep82 Posted April 15, 2015 Author Share Posted April 15, 2015 Changed coil dizzy cap rotor every thing the ignition side and it still gives a miss at high rpm I am lost now?I am using 540 injectors and emanage ultimate could injectors be to big for my set up dumping to much fuel near red line? Mapper said it looked like coil or something but I've changed everything? Quote Link to post Share on other sites
Stu Posted April 15, 2015 Share Posted April 15, 2015 (edited) Take a look at the pick ups for the trigger wheel inside the dizzy - any metal swarf or corrosion will not be helping. Edited April 15, 2015 by Stu Quote Link to post Share on other sites
tommyep82 Posted April 15, 2015 Author Share Posted April 15, 2015 Thanks I checked both of them that I had on car both look good and still the same Quote Link to post Share on other sites
tommyep82 Posted April 16, 2015 Author Share Posted April 16, 2015 Sorted lads imagine the jumpers inside ecu for knock sensor were wrong, imagine it was mapped before like this and no problem, but my ct9 hybrid used to run out of puff at 6500 so had no need to rev harder Quote Link to post Share on other sites
