My car was a 2002 Roadsport 1.6 K series Mems ecu-eu3 until the dreaded H.G.F. started to show signs of developing. As i realised that this problem would only get worse and ultimately fail i decided to bite the bullet and kill two birds with one stone thus i went down the slippery path of upgradeus! So off came the head,hardness tested,fire ring peened,gas flowed and polished (as per the DVA Power website) retaining the standard valves but profiling the back face and skimmed. Install SS cams (inlet set to 0.060thou and exhaust 0.047thou ) Vernier pulleys ,new belt,bolts,water pump etc. 52 dia throttle body. Remap ecu to SS spec,carried out by Z&F (by post 48 hr turnaround) Repipe cooling system to design shown in Lowflying mag. Reassemble complete with new fluids. To my surprise and relief she fired up first time and after checking for airlocks etc let her get up to running temperature. I then noticed that the tickover was lumpy and hunting,i was not to perturbed at this point as i had read a thread from oilyhands stating that "The idle will worsen when the timing is corrected since the inlet valve opens earlier and the plenum is subjected to reversion pulses at low RPM since the cylinder still contains exhaust gases under pressure.The ECU is calibrated on manifold air pressure so It sees a confused vacuum reading,hence the hunting around " If the car is stationary and the engine speed gently increased to 3000 RPM it is possible to hear a slight intermittent roughness. However if the car is driven steadily on the level with little or no throttle in any gear to a max 3000 RPM this can manifest itself into a lumpy,hunting kangarooing driving sensation that can only be corrected by either riding the clutch or accelerating,in fact the car comes to life when revved to the max and pulls like a train,but i think the problem is still there on the overrun. At present the car is impractical to drive around town etc and I've come to the conclusion that I'm losing the pleasure aspect of using this car. I'm at a loss to know which avenue to take to correct this. My thoughts are 1 Reset the cams to be less aggressive (but loose power) 2 Is this an ECU problem (remap) 3 A suggestion by a fellow club member I met at Sherborne Castle Event was to replace the coil packs (I feel if this was the cause then this would be more noticeable under load, ie accelerating,and not on tick over where there is less load on the coils) 4 I've ruled out the lamba sensor as i have just had the car mot'd and the examiner said the emissions test results were better than a lot of the modern cars Any thoughts or input would be gratefully appreciated Sean
