Pontiac (GM) vehicle produced for the 2006-2010 model years.

enter image description here

The (General Motors) Pontiac Solstice is a small 2-seater sport car design. It shares it's platform with the Saturn SKY and Opel GT. It's production run was from 2006-2010, though only 30 vehicles (to include all variants) were produced in 2010 before production was shut down. These last vehicles were used as corporate and evaluation cars, then later sold at auction to the public.

The Solstice came with two engine options: 2.0L and 2.4L. Both are inline four (I4) cylinder, Dual Overhead Cam (DOHC) engines. There was also a 2.0L twin-scroll turbocharged version for the GXP (2007-2009) which produced 260hp/260lb-ft, which at the time was the highest horsepower to cubic inch displacement motor GM had produced (2.1hp/ci).

Solstice! Car starts to run rough after hitting the gas, intermittently.

So, after putting the A/C-delete belt on to take my POS A/C compressor out of play, everything works great: No frightening rattle / clanging from the engine bay Idles smooth Sounds like a brand new engine. Which it should, since I've only put about…

06 Solstice - weird hesitation / bogging under heavy throttle

I wonder what percentage of the questions here are from me about this car... When I try to accelerate with more than about 60-75% throttle at lower RPM (say, under 3k or so), the car starts to accelerate, then acts like there's a fuel cut. This will…

THAT Solstice - What causes an exhaust back-fire?

I had some oh-so-wonderful hesitation and an exhaust backfire this morning. The car wasn't really up to temp - it had been running for about 15 minutes and it's ~68F this morning. Some potential causes I've found are: Sticking exhaust valve Running…

06 Solstice LE5 DTCs

My love-to-hate-it relationship with the Solstice continues. I was having some issues with apparently-random warnings (ABS light, weird DTC, gas cap warning when the gas cap was not loose). The issues temporarily (for a few days) disappeared. Since…

Shop replaced engine, blew about six weeks later

A local repair shop recently replaced the engine in my 06 Pontiac Solstice. They obtained a used engine from LKQ. I'm not sure how many miles the replacement engine had (unfortunately). Wednesday night, the engine blew. Under light acceleration, I…

Solstice - Can an exhaust leak cause (really bad) hesitation?

My Solstice says "hi everyone." Moving on. I've had some really rough starting over the past month or so. I hadn't had time to really look at it until a few days ago, when I noticed the downstream O2 sensor harness had been cut, I'm assuming by some…

New engine and clutch, have weird vibration @3K RPM

I just replaced (well, had someone else replace) the engine in my 06 Solstice. The engine runs great for the most part (will open a separate question about that), but there is a weird vibration at about 3K RPM. The vibration disappears when the…

Non-blown blown head gasket

06 Solstice, 2.4L Ecotec LE5 (GM inline 4). Again. I had an overheating issue recently, where the temp went from ~200 to ~290ish very rapidly. I shut the car down and had it towed home. A few days later, when doing a compression test, steam came out…

Removing head while maintaining timing chain tension & position

I'm pulling the head off of the Solstice (2006, 2.4L Ecotec LE5), and would prefer not to have to remove the timing chain cover to get the timing set correctly. The last time I did this, the engine was out of the car. I would prefer not to pull the…

ECM voltage, spark spike

When the car was idling in the garage this morning (hooked up to HP Tuners), I saw a spike on the "Spark" graph at the same time as the car stumbled. "Control Module Voltage" also went from > 14 down to 13.69. Not a massive difference, but I don't…

06 Solstice (Yay) Fuel smell after hard acceleration

Vehicle: the ever-present 2006 Solstice with aftermarket turbo. When I lift after hard acceleration, I can smell what I think is gas for a few seconds. It dissipates quickly, but is disturbing. A few days ago, I popped the hood and noticed one of…

2006 Pontiac Solstice - Wipers turn on by themselves

Here's a new one: Three times in the past week, the wipers have randomly turned themselves on. Each time turning the switch on and back off has fixed the issue. I haven't seen anything else indicative of an electrical problem. Suggestions? It's a…

Cleaned throttle body, MAP sensor suddenly dead

(Solstice) So, I cleaned my throttle body with brake cleaner. I thought it was carb cleaner, but I am apparently illiterate. (Honestly, I'm not sure what the difference between them is.) I was very careful not to get anything on the throttle control…
