View Full Version : High revs at startup on a '96 Cobra

Merry Christmas to all!

I am new to this list, having recently purchased a '96 Cobra Convertible, 30k miles, one previous owner, very good condition, garage kept, regular maintenance, etc.

This is a great car, despite not having any mods (yet).

One issue that perplexes me, though, is that on startup, whether a cold or warm startup, and whether the weather is warm or cold, revs jump to 2200, then almost immediately come down to idling speed (around 1100 rpms). If the car is warm, and I shut off and restart, it still jumps to 2000 rpms before settling down to idle. I know this doesn't sound like a lot, but I have never seen this before in any of the vehicles I've owned, and I cringe every time I fire it up.

Is this normal for a Cobra? If not, what could be the cause?

The reason I was given for this is that it revs high on startup to get oil to the heads quick.

It is more or less normal for all modern fuel injected engines. It is a startup procedure the computer runs through. It emulates the manual, mechanical, or electric chokes from the good old days of carburetors where an engine needs to run a bit rich and at higher revs when cold. As long as it settles down to around 700-80 RPM's after a bit of time all is normal.

2200 RPM seems a bit high, I have not owned or started a 96 mustang so it is probably normal. Typically I have seen 1000 to 1500 on the 01 and about 1000 on the 04 for a few minutes at start up.
