Hello everyone. Pretty new to LGT but have owned a couple subi's
Okay so I got rough idle, and Missfire in #2 & #4. Ive replaced all 4 coils, spark plugs and MAF. Idle is a little better but still have misfire in #2 & #4. Took out both injectors and took off negative to battery. cleaned both injectors with carb cleaner put them back in and started it up. No cel, went for a little cruise and cel flash a couple times then goes off. Hit the highway cel comes back on, but under wot it will go away sometimes. (I don't wot all the time so just seeing what it does)
When I get home I let the 05 lgt idle in my driveway, no cel only rough idle. I rev it around 3k rpm cel flashing. Let it idle and it goes away.
I then turn it off and let it sit over night. In the morning I start it up and solid cel comes on and stays on.
Today I am gonna switch injectors and see if it follows. I got a new timing belt kit coming in, in hopes that it gives a better idle. It got 190k so its basically time anyway.
The guy I bought it from said he never had issues until he got it tuned. He claimed after a couple pulls it threw misfire codes. So I sent my tuner his final log and he went through and tweaked it (a lot) he said it was pretty sloppy job. So hopefully with new tune and timing belt it will calm down
