Please Help !! Car running really RICH (long)
I've been tuning my car for the past 2 months by buring my own chips, and I've been luccky enough to get my BLMs within +- 2%, so I decided to play around w/ the PE tables. Updated the table so that calculated AFR is 12 instead of the 11.xx current setting. I then proceeded to run the car lightly and collect more data. I noticed that the BLMs at idle were starting to run 10% into the rich side. I reinstalled the previous chip hoping to get the car back to the original settings, and the car was running in BLMs 15% into the rich side (BLM=108) :confused: Do you guys think, I screwed up my memcal during the re-installation(no codes) or do I have a stuck injector :eek: . I've read some post, where Accells injectors stay open. The car runs, but it runs really bad. I don't want to drive it until I solve this problem. I don't want to screw up my new motor( hope it hasn't happened :cry ). I'm planning on puling the fuel rail & injectors and putting a a cup under each one and see if any is stuck open. Will this diagnose the problem correctly ? Please advise, any input will be greatly appreciated. (There goes the weekend :sad: )
thanks,

An easy way to check for a stuck injector is to put your finger in turn on the back of each injector's connector at idle. All "click" pulses should feel about the same. A stuck injector of course shouldn't pulse at all.

Re: Please Help !! Car running really RICH (92LT1Roadster)
got the car running better again. it wasn't the injectors. it was my ecm piggy back adapter. after pulling the rail and checking if any of the injector is leaking, i decided to pull the chip and clean all the contacts. reinstalled, and everything worked okay again. i will probably order a new piggy back from Craig Moates (this one is from JET). by the way, when i was testing my injectors, the resistance changes with the engine warmed up. i was seeing up to 22 ohms, but it was around 17.3 ohms when i checked them cold. is this normal ?
