New Owner - Help! :(
 

Hiya,

wish my first post was on a more upbeat note.

Picked up a 92 (Japanese Import Twin Turbo) RX-7 tonight, and after only 10 miles, I lost a rotor (also managed to get pulled by the cops for no tax/nct on the way, but that's another story!).

With a little help, managed to work out that the engine was running (badly) on 1 rotor, and that going by the smell from the exhaust, the dud rotor was spitting fuel/air straight into the exhaust.

Also pulled each set of spark plugs - one side - same as before, other side - nothing.

So. The car has hardly been used in a year, and I expect that it's Spark plugs/HT leads, and i'll start by replacing the plugs and working my way back out to the coils.

Any other hints from knowledgeable folk would be appreciated!

The car is now parked up at work (lucky I wasn't far away) and I really want it back on the road!

Thanks!

Jim

You sure the motor isnt blown? Sounds like its time for a compression check...

Or the first thing to check...Map sensor vacuum line...

+1 Definately....

I'd agree with the MAP, but I've never tried driving more than pulling out of a parking space with it disconnected. If you pulled out and didnt' notice anything, then the MAP was at least connected at that point. The MAP sits on the driver's side firewall and will have a vac line dropping down and going towards the passenger side to the back of the intake manifold. It should be easy to tell if it's disconnected by pulling on the line (just a little) and seeing how much resistance you get. If there's no line connected to the downward facing nipple, then you may be able to solve your problems very easily. Just connect it to the line coming from the manifold that has nothing attached at the other end.

When my MAP was disconnected, I could barely move the car backwards without thinking I was first learning to drive a manual all over again. The MAP would also account for the clouds of smoke, because it seems it pretty much pours the ENTIRE TANK into the engine as fast as it can with the MAP disconnected. I saw the same cloud when mine was undone.

If you lost power while driving under normal conditions, I'm kind of at a loss. If you lost the power while you were under boost, then make sure any pressure lines are still connected. If you have a slightly loose connection in a pressure line, and it decides to walk a little under pressure, it can make a profound impact on how the car drives.

First, check the MAP, then check all of your main lines under the hood and see if there are any noticeable leaks. Check the small vac lines too to see if any are broken, rotted, etc. If you see no leaks, start the car, put your head under the hood and rev the engine with the throttle cable to see if you can hear/feel any leaks.

Once you do that, post back and let us know what you find, and hopefully one of the folks more educated than I can help you out.

And not that this post is any better.... but seriously....


Why did that deserve a post?

Compression test, then pull the injectors and get them cleaned.
