no smoke, no power, what the?
 
Here's my situation.

1. Just had clutch replaced on my 86 RX7.
2. Now, car hard-starts and stalls out if the accelerator is not pressed down.
3. Very, very little to no white smoke (therefore I don't think I blew a seal)
4. Mechanic at local shop says "there's no compression, don't spend any more money on it"

Now, I am not so quick to let it go at that. I am considering doing the "atf trick" although I would use the Mystery Oil instead.

I can drive the car, but it does sputter and has low power. But again, there is no significant white smoke.

I've been looking all over the web all week looking for some suggestions. Thanx!

Don't waste time dumping chemicals into the engine...Won't do any good, and could cause harm.

Sounds like the TPS is disconnected. Especially if this happened just after the clutch replacement. Check around the upper intake area and look for disconnected hoses, wires, etc. Also make sure the trailing and leading ignition wires are not reversed.

Have you actually done a compression test, or just taking the "mechanic's" word for it? Because there's a 99.999% chance that he or she is wrong.

all connections look ok. At this time I am just taking his word about the compression test. I'll be bringing my car home later today and will be spending time checking everything out. Right now the only way I can start it is by pulling the green fuse, cranking the engine, and then having somebody inserting the fuse. I hold down the accelerator to maintain at about 2,000 rpm and the engine sounds fine, just fine. I let go of the gas pedal and "putt putt putt" until it stalls out. Driving, first gear is fine but it backfires just a little bit when I go to second gear and it doesn't have much power. I'll keep at it!

is your afm plugged in? Clogged cat maybe?

Late last night my friend gave me a ride up to the shop where my car was. He gave me a push-start and I drove home fine (so long as I kept my foot on the gas pedal).

This morning I pulled the leading plugs and put in some ATF. Turned the engine a bit and put in a couple more drops. Now I let it sit, right?

I double-checked everything. The oil looks clean. The coolant is fine.

How do I check if the AFM is plugged?

I am not giving up on this puppy yet.
