Have searched the forums and thought I would post for additional advice.

Car will not run/idle below 3000 rpms (just dies), and really has no power above 3000 rpms. Use to have some of both, but has gotten worse. Near impossible to start and when you do, it just has no power.

Was driving one day and it died. Tried to start it and it flooded. It has never run real well and has always been hard to start or idle. But now, it is really hard to start, and has the issue above.

Reading the forum, so far we have:

1) Replaced the TPS
2) Put in new plugs/wires
3) Listened for compression in each rotor ( pssh, pssh, pssh). Sounds good
4) Checked for spark from both coil packs (good).
5) Changed out the ECU (had an extra)

Engine was rebuilt by previous owner and automatic was replaced with a manual. It has never rev'd above 6000 rpms while under load (driving). And now we have this issue making it not driveable.

I have not done a compression check with a gage, but it sounds good so I am leaning towards injectors. After running it, the plugs have a little carbon, but are dry.

Any thoughts are appreciated. Any additional questions will be answered as I need the help of folks on this forum to figure this out.

Thanks in advance.

Check for codes, and do an actual compression test. A low compression engine will still make a whoosh sound as the rotors spin.

Can I use a standard compression tester?

Thx

Nevermind...just read a few more posts and web sites. Will do the test and see how this looks..

might be fuel related, like you said check the injectors.

has the fuel pump ever been changed?
