SAAB 9-5 CEL - P0340, P1312, P1334
Hi!
So I recently bought a '03 Aero Stage 1, but then the problems started.
First was Random misfire error, also there was codes P1110, P1301.
Went to a workshop, there they found a vacuum leak, but changed all sorts of things -
Oil, thermostat, Intake Manifold Pressure sensor (new), Intake Manifold Mapping sensor (used)
Spark plugs (NGK Platinum ones, should I buy copper ones? BCPR7ES?)
fixed the vacuum leak from brake booster, changed the vacuum tubes,
Installed used 2005 DIC TK 3.7, as the old one was TK3.6 and started to give the misfire codes and cranking worse with every time.
It was fine first 20 minutes after leaving the workshop, could feel those ~280hp really showing themself for the first time, pushing me in the seat even without Sport mode on. Then, refueled, fired up the engine, and the CEL light was back on...
Went to my electric, and he gave me these codes - P0340, P1312, P1334. What should I do next? He says it's all DIC, but is it?
Completely new DIC is extremely expensive here. I bought the car for 400 € and new original DIC is 500 €, so another car :/
Is there anything I could do before buying DIC to get rid of those codes and get the performance back? Also, every time you start up cold engine, revs are triggering from ~800 - ~1500 till engine is warmed up.. is that related?
Thanks in advance :)
