Rancher Posted December 8, 2009 Report Posted December 8, 2009 (edited) Hey guys. Few of you might remember the coil igniter problem I was having a while ago. Well thats sorted. ATM, its idles, but barely wants to rev. Coughs, and farts doing it. I unplug the MAP sensor vacuum line and it revs a little better then it does plugged in, but still coughing. Also, unplugging one of the injectors yeilds no difference in idle. It also apears to be getting hot, pretty quickly. Please help. This is driving my brother and I nuts.

Rancher Posted December 8, 2009 Author Report Posted December 8, 2009 (edited) Unplugging the TPS made no difference in idle and reving. Unplugging the MAP electrical plug made a huge difference. It wanted to rev as best it could being flooded with fuel lol. Any ideas? Edited December 9, 2009 by Rancher Quote
Taz_Rx Posted December 9, 2009 Report Posted December 9, 2009 Sounds like too much ignition timing! :) That would account for the back-firing, why unplugging the MAP sensor improves it and the over-heating issue! Quote
Rancher Posted December 9, 2009 Author Report Posted December 9, 2009 Timing is dead on 10* BTDC. (Though, this is not putting a wire in the T and E1 plug things cause we can't find it...) Quote
930LLO Posted December 9, 2009 Report Posted December 9, 2009 Your timing might be out a tooth on the cam gears I had the same issue with my 4age and it was the timing, have you checked to see if you are 180 degrees out? Quote
Rancher Posted December 9, 2009 Author Report Posted December 9, 2009 (edited) Timing is spot on. The belt was not removed. So, it can't be that. edit: So timing could be out. Just reading around then, and it says I have to short some terminals, and then set the timing to 10* BTDC. Problem is, some DOUCHE bag did the conversion in this, and the wiring. So, I don't know what plugs I'm even looking for. Halp. Edited December 9, 2009 by Rancher Quote
Rancher Posted December 13, 2009 Author Report Posted December 13, 2009 You'll never guess. Wasn't the timing (Though, that was out) Wasn't TPS, MAP. Was the coil. Was too small.... For shits and giggles, we put a bigger one on, and it ran sweet. Quote
Rancher Posted January 3, 2010 Author Report Posted January 3, 2010 Me again. Lol.... Different kinda issues atm. Having the MAP allows the car to run. Poorly. But, plugging the map back in, it revs up to about 2k, then dies. Replaced with a new MAP. same issue. Really starting to be a bother. Quote
wan.7 Posted January 3, 2010 Report Posted January 3, 2010 Is the "new" coil "NEW" or is it just another coil? Sometimes it is better to just cut that option out and replace it with a brand new one of the correct type. If replacing the coil before made things better then perhaps all your problems could be coil related. Could also be the ignitor OR something as simple as a bad lead? Quote
4AGE_Keto Posted January 4, 2010 Report Posted January 4, 2010 It is a brand new coil.. took the original coil to Auto 1 and had the part number looked at and got the exact same one brand spanking new.. So the coil is not the problem anymore.. Could be the leads or maybe something in the dizzy or even the igniter Quote
