[QUOTE="ThA SkInNy, post: 1091726, member: 16625"] I just recently picked up a 1996 100% factory Cobra with just under 200k on the clock. I got the car for a pretty decent price I think...$1800....the car didn't smoke or look to be burning any oil when I drove it all though the manure nance levels on this car weren't all that great from looks of the poor filthy Cobra.. It's a 3 owner car but they were all members of the same family..lol I'm having some what seems to be fuel issues. I'm not throwing any codes that I know and I stilled scanned with a tuner. At light throttle my car is fine and will run all the way through the rpm's. if I give it sudden blips it will want to cut out. This only happens under load. It starts and idles just fine from what I can see and hear and will rev nice am normal in neutral. The check engine light was flashing when driving so obviously throwing some other codes. For now I have cleaned up all of the codes from not seeing an engine light yet but I know it can take a few heat cycles for some thi fa to show up as a cel sometimes. I have replaced some things because they were necessary and some things just because the car has some miles on it and I was given much info on the service of the car. MSD wires Motor craft plug Coils from a running car Fuel filter New 24lb injectors tps Cleaned MAF Cleaned IAC(mine has a vucuum line nipple facing the front of the car?) Mil eliminators Basani O/r X SLP Lm1's I'm thinking I'm needing to change the fuel pump but I keep hearing about low speed relays for the fuel pump and to check those. A code was picked up by an SCT Tuner for 2 speed pump/ low speed when I first got the car. I know there is one in the CCRM and there is another also somewhere around the dash or the ecu/pcm area.Lol so I also went to the parts store and picked up and new fuel pump relay...only problem is I can't find where it goes. Haha I haven't done a compression test yet because I honestly think the motor is in good shape. The car runs great in the middle rpm range but is really trash outside if that if giving it anymore than part throttle haha. It idles great and I don't here anything I haven't heard coming from it comparing other 4vs I've heard. If you guys might have any suggestions as to where that fuel relay is please let me know along with any other suggestions you may have for me. Thanks in advance! [/QUOTE]
