Drive Belts & Pulleys Replacement on the Infiniti G35 Coupe

Since the day I purchased the Infiniti G35 Coupe, there was a belt squeal on cold starts that would go away after a minute of the engine getting warm and would not appear until the next cold start. After some research, I found that it was due to the main drive belt not being tight enough.

The previous owner had replaced the alternator before my purchase, but had used his uncalibrated thumb to test for the belt tension. I wanted to make sure that the belts were new and proactively decided to replace the idler pulleys as well. This post talks about how to do that. If you just want to check and adjust the belt tension, you can skip to the last section.

This job is actually relatively easy, and can be done within an hour or two if you have the parts available. However, my car has some rust and the adjustment bolts needed replacement, which delayed the process for me.

Lower Oil Pan Replacement on the Infiniti G35 Coupe

I did another oil change on the Infiniti G35 Coupe but the oil leak that was happening from the oil pan drain bolt did not stop, despite replacing it with a new washer. So it was time to replace the lower oil pan so that the oil leak would stop.

This job is actually very easy, and can be done within an hour if you have the parts available.

Fix CEL codes P1128 and P1130 Boxster by cleaning MAF Sensor

The Porsche Boxster S started showing a check engine light (CEL) in May. I used an OBD2 code reader and saw that the codes were P1128 and P1130.

Luckily for me, there was an article in the May-June Porsche Club of America magazine (Figure 1) that mentioned this exact issue in their tech Q&A section.

Turns out it is related to the intake, and the easiest test is to clean and/or replace the mass air flow (MAF) sensor. Since a new MAF sensor is about $150-$270, I decided to clean it first to see if that fixed the issue.

However, based on other research it could also be an evap leak but this post is about the MAF sensor cleaning.

19 inch Wheels Install, Bucket Seats and Window Tinting

Over the last two weekends, I did a few important changes to the Infiniti G35 coupe. The original coupe came with a set of 20 inch aftermarket wheels and tires (Figure 1). So I procured the original 19 inch Forged Rays (Figure 6) from a seller about a hundred miles away a few months ago for $450, through Craigslist, which was a bargain. As you can see in Figure 7 that the 19 inch wheels look pretty good too.

Moreover, I also procured a pair of reclining racing bucket seats (Figure 9) made by Procar by Scat for about $280 on Facebook Marketplace. However, someone pointed out that these were knockoffs so I did feel a bit cheated! :( Oh well! These seats were in a Chevrolet Chevelle, so at least the brackets and sliders that came with it can be sold for something, and they look original since the part numbers are engraved on them.

To make myself happy, I decided to get the windows tinted on the car. I had been waiting for a while and feeling lazy to get it done and this Memorial day weekend I paid about $275 to get it done. 20% tint on the driver and passenger windows (Figure 8a), and 5% tint on the rear windshield (Figure 8b) and the strip on the front windshield (Figure 8c).

First Autocross in the Miata in 2022

I went for an autocross in the Miata today in the Norther New Jersey SCCA (NNJR-SCCA) club at Metlife Stadium.

I found the course to be more difficult than the earlier courses and it had several sharp turns. My performance (Figure 3) was not as well as I had hoped as I came last in my class.
