It states that the maximum varience permitted is 13 degrees. Image 1: ETM Software part number (updated confirmati...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

After confirming software compatibility and viewing VC7200 counters, I felt confident that that softwares are compatible and performed an ECM reset. (3minute interval procedure) At the end of said procedure, I was asked if the ECM-4038 error was still noticeable. Since I was not sure, I closed the w...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

It initially sounded like there is pressure build up that is slowly released while the car is off. I would need to replicate and find a better angle to demonstrate it, but im not sure if its currently present anymore. There were several loose hoses around the system. when the ignition is on and the ...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

The pencils were not grounded as suggested. All plugs have an impact now. I went ahead and performed another hot compression test. Oil temp gauge pictured. IMG_2817.jpeg Surprisingly, the spark plugs heads are quite clean now. Pictured, but not clear. They are white IMG_2822.jpeg Results are as foll...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

correct. I have been told they must be grounded with the 10mm bolts, so I will do some tests again today.

Here is another video of the cylinders. are the crowns normal, we are wondering ?

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

Some updates. After a 10min drive warm up (oil between 60-70% of meter), I attempted some tests. 0. The car does not drive above 20-30km/h. There is very little power. 1. First, I attempted the glove test. It was not inflating, nor was it being sucked in. It seemed to be alternating (inhaling & ...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

The first mechanic claimed to have performed an extensive diagnostics.

Again, I trust nothing he says, but we may find something of use from statements at this point. (he also claimed he was able to get the car up to higher (highway) speeds, but I have never seen the car exceed 30mph)

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

Another (good) surprise. Following are photos of spark plugs and some endoscope photos of the cylinder area. ELECTRONIC COMPRESSION RESULTS: Cylinder 1: 160 (8 revs) Cylinder 2: 171.4 (9 revs) Cylinder 3: 176.2 (8 revs) Cylinder 4: 181 (8 revs) Cylinder 5: 179.9 (8 revs) It would appear we have pres...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

All spares were included in the deal. To be honest, the purchase and experience with seller was such a blessing of a first car purchase. I did not know how good the maintenance and spares pile was when I first found the deal. I'm not even comfortable discussing what I paid publicly because i joked w...

Re: Engine Shaking & low power - 2000 s70 FWD Base Model

Continuing towards pressure diagnosis, but first; mini update: Funny because you have to laugh :D ; When I tried to attack the screws on the on the fuse box, the bit almost immidiately fell into the engine bay, but I never heard it hit the floor. After a few minutes of looking with the endoscope, I ...
