Sandham Posted March 18, 2014 Share Posted March 18, 2014 Hi ive been strugling with a misfire and some hesatation for some time now, running a td04 under fuel cut at stock fuel pressure.. So far ive changed the plugs, fitted trd leads, a brand new oem king lead, new dizzy cap and a new rotor arm. However im still experiencing the problem. Its very random and intermittent and seems to go when at very small amounts of throttle or wide open throttle :/ Im struggling for ideas now and would really appreciate some help Quote Link to post Share on other sites
5e colin Posted March 18, 2014 Share Posted March 18, 2014 hey sandham check your plug gap first if there grand check for water consumption ( fucked headgasked ) seeing u changed the rest for new that eliminates that i had this to before long ago and changed evry thing and it was still there in the end i was leaking water in mi cylinders !!!

Sandham Posted March 18, 2014 Author Share Posted March 18, 2014 Plugs are gapped to 1.1mm from the box, do you think it would be worth dropping the gap a slight amount? Quote Link to post Share on other sites
5e colin Posted March 18, 2014 Share Posted March 18, 2014 sure i run 0.8mm gap at a bar !!!! the bigger the gap the more chance of spark blow out resulting in a mis !!! let me know how u get on wit a smaller gap Quote Link to post Share on other sites
Sandham Posted March 18, 2014 Author Share Posted March 18, 2014 Im gonna have a sniff test done tomorrow for peace of mind and will also drop my gap to 0.9 Quote Link to post Share on other sites
Sandham Posted March 19, 2014 Author Share Posted March 19, 2014 Passed a sniff test this afternoon so thats crossed off. Will try my coil next Quote Link to post Share on other sites
dangeestarlet Posted March 19, 2014 Share Posted March 19, 2014 I have a coil £10 posted Quote Link to post Share on other sites
Sandham Posted March 19, 2014 Author Share Posted March 19, 2014 You got paypal mate? And does it deffo work? Quote Link to post Share on other sites
5e colin Posted March 19, 2014 Share Posted March 19, 2014 thats great that it passed the sniffer test if the coil dont solve it then the only thing i can think of is that you have a sparkplug seal leak and oil dripping in there cousin a misfire ??????? Quote Link to post Share on other sites
dangeestarlet Posted March 19, 2014 Share Posted March 19, 2014 Yes works fine mate, what one you after as there's 2 screwed together, coil or ignitor? Quote Link to post Share on other sites
Sandham Posted March 19, 2014 Author Share Posted March 19, 2014 (edited) Ive reduced the gap to 0.9 and its helped abit but still just some slight hesitation occasionaly. I did notice one of my spark plugs had a tiny amount of oil on the top half so maybe its that? It never crossed my mind to be honestAlso id be after both parts mate because i dont know which is at fault Edited March 19, 2014 by Sandham Quote Link to post Share on other sites
dangeestarlet Posted March 19, 2014 Share Posted March 19, 2014 Ok mate are yours clip type leads or boot type? Quote Link to post Share on other sites
5e colin Posted March 19, 2014 Share Posted March 19, 2014 ha sure kid if there is a bit of oil on it the spark will jump cousing a miss give it a good clean 2morow and check again Quote Link to post Share on other sites

4efteboost Posted March 29, 2014 Share Posted March 29, 2014 you need a timing light like this.. http://www.eurocarparts.com/ecp/p/tools/car-service-tools/diagnostic-tools/timing-lights/?SEATL85&0&t5_401 would be better if you could find a friend or a local garage to take a look though. 5 min job really Quote Link to post Share on other sites
