Alright so I'm gonna start listing off some issues and I need some input here. I don't have any idea what's wrong
First off of you can't see my signature cuz you're on tapatalk here's what I have done to my pickup:
Supercharger, LT headers, 214/228 114lsa cam, 3000rpm circleD stall, exhaust, intake, tune, 4.10 gears, 305/55/20 tires and a 6in lift with a 1.25 body lift
Issues:
1. Torque converter only locks up when I'm going 50mph. If I accelerate to interstate speed right away it doesn't lock. I have to stay between 50-55mph for about 2-3 miles for it to lock. Tune? Converter maybe? Whole transmission?
2. Throttle position sensor code. P0121. It's off and on. I replaced the sensor and it still comes every once in awhile
3. Running unbelievably rich. Every time I start it I feel like I'm huffing gas. Also my friend told me it blows black smoke during acceleration.
4. Sputters during acceleration. There's no smooth acceleration in this thing passed 3000rpm. Also 3/4 throttle has more power than full throttle.
5. Abnormally rough idle, even with my cam.
6. Hard starts on occasion. It's like a dragging start. Sometimes it'll start then die right away.
7. Extremely bad gas mileage. Before the supercharger install I got 12-14 highway (10-11 interstate) now I get 6.5-7.5 on the interstate. It's ridiculous.
Notes: It threw the cam shaft position code after the cam install but Justin did a tune for me that removed the code. I'm wondering if there isn't a problem there. It ran like it was either too advanced or there was an issue in the position solenoid.
Also most of these issues either occurred strictly after the supercharger install or became worse after it.
So what do I do? Burn it and get insurance? (JOKES!!)
