So I got this little beast running last night.
I thought I had a huge problem since the car did not want to hold idle whatsoever and it sounded like it was misfiring terribly. I shut everything down, rechecked my connections, went over everything with a fine tooth comb and all was good. I started her up again and still a very rough idle that will not stay on unless I give it throttle.
So I sat back for a minute to thinkk of possible solutions to this little problem and decided that letting the car run with me feathering the throttle would allow the car to figure itself out. Sure enough, it did. The idle picked up to a high 1200-1500 rpm then settled down to around 700. I let her idle for a bit, checked fluid levels, then decided to take her for a spin.
Another minor problem arose, and this time it was me only being able to get into 2nd and 4th gear. I pulled back into the garage and checked the shift linkage and one had popped off. Popped it back on and drover her again. First gear felt great. I wasnt able to drive too far as I have not insured the car yet (I havent driven the car since I bought it due to it going straight through the swap process as soon as it hit my garage floor) and it was raining cats and dogs last night.
So, when I get home today I will have it insured and take her around town. Unfortunately I dont have a base line to determine the difference between the 2.5 and 3.0, but I can say that the 3.0 feels quite nice, and the exhaust note is pretty unique.
