adie205 12 Posted February 13, 2006 (edited) Could really do with some advise, im totally puzzled! Rite, it starts fine high idle then comes down to just under 1k But when idling you can hear a slight miss from the exhaust and the engine rocks a tiny bit. Driving is fine gets up to temp well and stays at a good temp, best its ever been until you stop (eg to get some fuel) then it starts fine but feels really lumpy, it misses, backfires and when i put a load on it sometimes stalls! Really have to ride the clutch and rev it to get it going, and when it is going you can feel the engine jumping all over the place (makes me look like a learner!) Then after a couple of minutes of driving its fine again, that is until you get to lights then it starts doing it again. Also when i let off when driving it feels lumpy as the car slows? Really bugging me Going to look for an air leak but if its not that im stumped Done a search and ive replaced most of the common problem parts Its had new Coil Temp sensor Ht leads Plugs Ign amp Any ideas please Yet again its back in the garage with the bonnet up and my girlfriends moaning Edited February 13, 2006 by adie205 Share this post Link to post Share on other sites
boombang 2 Posted February 13, 2006 maybe needs a re-tracking of AFM? Simplest way to check for an air leak is remove air filter, cover end with strong piece of plastic thats a lot bigger than the hole - if the engine carries on running then its got an air leak.

adie205 12 Posted February 13, 2006 Nice little test that, will give it a whirl, got my doubts tho because it wouldnt really explain the temp thing cheers adie Share this post Link to post Share on other sites
boombang 2 Posted February 13, 2006 My first guesses would have been coolant temp sensor and inlet temp sensor but you done them. Does sound strange! Share this post Link to post Share on other sites
adie205 12 Posted February 13, 2006 Yeh i agree, feels like a sensor throwing it all out. havent heard of an inlet temp sensor tho, ive only changed the blue temp sensor because the emissions where high. cheers il do a search Share this post Link to post Share on other sites
d-9 0 Posted February 14, 2006 As said above, afm is possible, fairy sure thats whats causing the hesitance and running problems on mine. Other obvious one is the cap and arm. Share this post Link to post Share on other sites
C_W 3 1 Cars Posted February 14, 2006 Recently my low speed hot misfire which got much when on track (ie hotter) and became a misfire at all revs turned out to be a rotor arm. My old one didn't look worn but the new one cured the misfire completely. Share this post Link to post Share on other sites
adie205 12 Posted February 14, 2006 Ah thats an idea, hadnt really thought of that because the cap and arm are pretty much new although saying that they are non gen from a place called cas, so that could be an issue Will replace them both as a process of ilimination afm is also something i hadnt thought of, will give it a clean and check track. fingers crossed, will spend a day on it tommorow. thanks for taking the time to give me some advice will keep you all posted cheers adrian Share this post Link to post Share on other sites

adie205 12 Posted February 14, 2006 Dodgy/Loose fuel injector wiring caused mine to hesitate/ misfire occasionally Nice one, will ad that to the list, the power of forums Awesome Cheers mate Share this post Link to post Share on other sites
205007 12 Posted February 14, 2006 sounds like its running rich on idle to me, id definetly check the coolant temp sensor and retrack the afm too worth looking at the plugs to see what state they are in too this will give you a clue Share this post Link to post Share on other sites
adie205 12 Posted March 2, 2006 (edited) Rite at last i think ive sorted it fingerscrossed hopefully this will help someone in the future, the problem ive been having has got progressively worse to the fact that it failed to start at all after cleaning the spark plugs, cleaning all earths and electrical contactsand the afm, i found the multiplug in the coil looked a little dodgy! a changed it for one i had on a spare loom at it fired up first time and runs like a dream (for know anyway) Also changed the cap an arm because although they were new they were mickey mouse, this has also made a massive difference So might be worth checking if your having the problems Thanks for everyone help Fallen in love with the pug again cheers adie Edited March 2, 2006 by adie205 Share this post Link to post Share on other sites
