Just got around to inspecting the cams I pulled a couple of weeks ago from my 7 bolt. The previous owner claimed they were 272's, but they looked stock to me. I noticed a few numbers stamped on the end of the intake cam though, wondering if anyone could ID these for me or if those numbers are of...

I'm looking for some suggestions on the source of this whine coming from the timing belt area. I've just changed the timing belt along with the idler and tensioner pulleys and auto-adjuster(Gates belt, Dayco components). Previous owner cut the B-shaft belt and put a bolt where the tensioner...

I know these are nearly useless, but I got this and an autometer boost gauge for free. I went off of a few diagrams and am sure it's installed right.1: The led stays at full lean until the car is moving and past 1500 rpm. Revving in neutral doesn't change it.2: When I'm not giving it any...

I just picked up a Palm M100 and Pocketlogger cable/software. I'm still learning how to read and understand the logs, and I'm not quite sure if I have the saving/uploading figured out yet.My engine has recently started to randomly bog down and/or hesitate. I double checked my vacuum hoses...

When I got my car, the a/c tensioner/pulley and belt were off. I bought and installed those, but the a/c hasn't been blowing cold. I finally picked up a Pocketlogger and it doesn't show the a/c clutch light flashing on/off when I turn the a/c on/off. Anyone have any suggestions where to start...

Lately, I've been noticing a strange squeaking or rubbing noise from the engine. It sounds like it's coming from the power steering/water pump area, but I can't quite figure out where, or what it could be. It doesn't seem to make any noise when first started and idling in the morning, or while...

I know it's possible to have power to the pump with the key "ON", instead of just while cranking and running, but is there a reason why I don't see anyone doing this in any of the write ups? Does the ecu/main relay have to be the one sending a signal to the pump, or would any turn on source do...

I was out checking the ecu for damaged caps etc. today and noticed it looked factory-new inside. Someone on another thread mentioned I should check the underside for soldering to see if the caps were ever replaced, but that also looks factory-new, so I got curious and started researching the...

My check engine light has been coming on intermittently the last couple of days and I finally got around to pulling it today. I used my digital multimeter set to 20k ohms, which seemed to work. It would start out with 1 quick flash, than pause for 2-3 seconds, followed by 2 long flashes, than...

I found these two plugs hanging disconnected the other day and have no clue what they go to. They're both behind the intake manifold, loomed into what seems like the main or injector harness. They must've been like that since I've had the car, but it's not throwing any CEL's and don't seem to be...

I've been noticing whenever I'm around 80% throttle and floor it for some extra oomph, I hardly(if at all) notice a difference.. I was out on the highway late last night and was noticing that when I floored it (at highway speeds), the engine didn't seem to pull as hard as I thought it should...

This is my first time owning a turbo DSM and I'm just getting to know it. The car is mostly stock, except a big 16g and modified air box. It's boosting 8-10 lbs and power comes on strong, but seems like it's lacking guts over 5800 rpm. What should I expect with the powerband? Is this normal?

I just picked up a near stock '91 FWD GS-T. It has a big 16g on it, and a cut air filter canister, but that's it. I'm having a couple problems that I hope to get some insight on.When I get into boost at WOT, I hear a hissing noise that almost sounds like it's inside the car, right behind the...
