Doh! I was thinking 92 SD.

87 300D

Well, my boost STILL isn't right. I have a gauge and all the bits to install it, and will do so tomorrow. This is driving me nuts. It boosts well around town, it seems, but once I get up to highway speeds, it just runs out of steam. 55-65 can take ages, and I have to really stomp on it to get it to kick down to 3rd, too. This is getting old. All those transducers and switches are a real joy to troubleshoot!

If I was local I'd bring mine over and compare. Don't give up. It will come around.

Thanks!

I won't give up on it... but the fact that it's intermittent is what's got me baffled. When it runs right, it's a joy to drive. With no boost, though, it's a real dog!

oh.. Yeah.. No turbo = DOG. You know you could leave the boost gauge connected and see whats going on. Check rpm/boost pressure. Boost should kick in around 2200 RPM. When your up to speed it levels out about 2 PSI. Check for cracks in hoses and the rubber fittings. Have you pulled codes again?
