I don't drive a Turbo (yet), but 10-15 seems mighty low to me. I think my friends TII idles at 8(+-1)

Seems your running rich, also have you removed the smog stuff out?

diabolical1 07-15-07 02:56 AM

is that from the T2 you have listed in your siggy?

what heat range are you using?

assuming your ignition is up to snuff, before you condemn the engine, i'd say try soaking the motor is Seafoam for a day and then run some in your fuel through a couple tanks and see if the compression gets any better, then post the result.

ur running rich. Get the plugs clean and make sure you have a strong battery, starting system and charging system. After getting the plugs in, see if your fuel pressure is good KOEO and at idle if possible. Specs can be found thru the stickies on the forum. From the symptom you've said, it sounds like a low battery voltage. But dont rely on that, do some tests. Determine either it is bad spark, or fuel... Because you can start the car, means timing should be fine. So other than that, its either fuel or spark. Let us know how this goes.

10 on a stock port motor is VERY low, it should be in the 17-19 range ( Remember that is stock ports only)

I only see 8-9 on my BP motor.

ryderX 07-15-07 06:42 AM

just relocated my battery, brandnew yellow top.

"assuming your ignition is up to snuff" not sure what you mean by this, but its just everything stock no ign

im thinking its a spark problem because, it takes some tricky fuelpump swiching/ throttle to get started.

but ill play with it some more after work and let you guys know how it goes.

ryderX 07-15-07 07:20 PM

well now i can not even get the car started. it will pull start and start right up, run fine. going to go get new plugs and see if that helps now.

ryderX 07-15-07 10:27 PM

alright got some seafoam, and new plugs. put some seafoam in the engine let it soak for a while, then turned the car over and blew it all out of the plug holes. alright. put new plugs.
turned it over, and over got it to start fairly easy! alright excited!
took it around the block to warm it up so it did not flood
got home turned it off, could not get it to start again.
push started it, got it started went to loaf got some gas.
so i was going around the block again, and suddenly as I shifted in to second it hesiated then POP and then it started to bog down I just left the car where it stoped at and ill get it and test to make sure it’s a goner
what a sad night

ColdSeven 07-16-07 01:19 PM

man im having the same problems i can't get mine started at all...i cleane dthe plugs, tried turning it over and nothing so next day i pulled the plugs again...just as bad as they were before.

sly-sa22c 07-16-07 05:50 PM

sounds similar to what's happening to mine.

it seems to just be running off one rotor. pulled the plugs and sure enough the two in the number 1 rotor were fubar. new set of plugs and the problem is still there.

gonna replace both coils and rebuild the dizzy which will hopefully fix it. if not the motor = fubar and i = over it :(

wigan_warrior5 08-07-07 05:50 AM

^^ thats insane lol, I have the same prob aswell, just put new plugs in still no start, did spark test and found no spark coming from one leading and one trailing lead (seperate rotors) just ordered some new leads, wil post up details of results. Also i think mine has been over fueling aswell but my AFM coil has been tamperd wiht so im going to try get a replacement one.
