Hey- my friend greg sent me this regarding an a4 1.8t he's been trying to fix... can anyone help? if you have any insight, reply here or by email to glane5@worldnet.att.net

thanks

Alex,
I have this Audi in my driveway that I put an engine in and I am stuck.
I was hoping that you could do me a HUGE favor and put this out wherever on
the web you might think I could get some help.
Here's the situation:
1999 Audi A4 1.8 liter turbo.
Timing belt broke, snapped off a valve, trashed the head and one piston.
The car sat for a year and a half.
The engine was rebuilt with another head (long block)
It is back together and in the car.
Idle is steady at 700 - 800 rpm but rough.
Exhaust sounds are equally not smooth.
It pulls a steady 20"hg at idle (which I believe is low).
Otherwise the vacuum gauge indicates normal response (including boost)
It will rev to higher RPM without load but is sluggish off idle.
When driven, power is limited off idle but gets better with rpm.
Changing plugs had no effect but the plugs indicate that the mixture is
rich.
Check engine light is lit during warm-up and then blinks.
Timing crank to exhaust cam is correct.
After one lap around the block (averaging 3000 rpm), several spots on the
first cat were starting to turn cherry red.
Before I spend more time (or head for the dealer), I was hoping that you
might know some web sites where I could get some help.
You can post my email address. (glane5@att.net)
Hope that all is well with you. Alex D. I copied you in case I did not have
Alex M email address correct.
If you can help me, thanks, I appreciate it.
Greg

 

02 sensors shot..


he needs someone with vagcom to read out the codes.

 

FLASHING CEL= misfires, possible coil problem sounds more like the ICM check the codes!!

 

20hg = normal

 

20 in HG is good. I saw mine at 11 in Hg the other day.

I was also north of 11000 ft elevation though.

 

2nd find someone with a VAG that can read the codes and further pinpoint the issue.
