    03 996TT
  1. Thanks for the welcome! Truth be told, I've been lurking for quite a while. I wish I could contribute knowledge like I could when I was building and racing TT Supras. Anyhow, the stutter I'm experiencing happens generally at lower RPMs and occurs when I change between all gears. It's like I shift into gear, start to apply the throttle, and then, bam, the engine feels like it cuts out for a half-second and then it recovers. A corresponding oil pressure drop (judging by the guage) occurs at the same time. I'm running the factory spec plugs - they were replaced 15k miles ago. I haven't checked the coil packs and I don't have any mods. I've heard about the variocam stutter, but this reminds me of a faulty distributor that couldn't distribute the electricity properly and caused the engine to hesitate. I know this car uses coil packs, so I'm using this illustration as an example in case anyone knows the type of stumble I'm talking about. Russ
  2. Hi everyone, I'm new to the forum. Very impressive collection of users, post and knowledge! Anyways, I have a 03 996TT that now has 53k miles. I've owned the car since 18k miles (about 2.5 years) and I've had the same problem since day one. The problem is that when I change gears and start to give it a little gas that the engine suddenly stumbles for a fraction of a second. The oil pressure guage drops quickly and then resumes its regular pressure reading. The same stumble happens when I let off the gas while in the same gear and then begin to slowing accelerate again... the engine stumbles, oil pressure drops quickly and then recovers. I've taken the car to several dealers who have not been able to figure it out - perhaps because the computer isn't throwing off any fault codes - and without codes they are too lazy to diagnose the problem. The problem is really annoying because its feels like a bucking bronco - just not smooth acceleration at all. Since there are no error codes, I can't seem to find anyone that can figure out what is going on. Has anyone experienced this problem and does anyone know what the issue could be????? Thank you! Russ
