Car was running really bad falling on it's face and idling around 400-500 rpm while I had it about 450 miles away from it's home to get some detailing work done. So had a local guy adjust tune and fixed a ground and vacuum issue at the same time. Got car back in that area (my parents lived there) and had it stored at my dads warehouse for a few months and car ran great.
My parents trailered my car back to me about 450 miles away back home and car wouldn't hold an idle and dies as it comes to a stop. Have to two foot it to keep it running while driving. Very frustrating but guy that was doing the tuning out in western Nebraska said O2 sensors could give me problems and wondering if this is just my luck. Don't know if the elevation and climate changes are affecting the tune? Tuned at about 3500 ft and now at 1000 ft or round about.
Here's a run down of the motor/drivetrain:
Heads - AFR Mongoose 230cc / 62cc
Injectors - 60# FAST
Intake - NW 102MM
Throttle Body - FAST 102MM
Plugs - NGK TR55
Fuel Pump - Aeromotive Stealth 340
Block - LQ9 4.03"
Cam - Comp 243/251, .624/.624, 111+1 LSA, 110 ISL
Crank - Lunati 4.00" Stroke
Pistons - JE 4.04, 12cc Dished for 11:1 compression
Rods - Lunati 6.125" H-Beam
Forgot something that might of use to mention and that is I currently have an E8 code on my Innovation Motorsport MTX-l gauge. It pops up and is on the entire time no matter if idling, cruising, or WOT.
Error 8 is listed as an Sensor Timing Error and says root cause is either 1. Sensor over-heating or over-cooling 2. Sensor Damage.
Hopefully this information provided can maybe shed some light on possible cause of idle issue.
