Hi all

Let me first say how much fun I had at the WCC autocross. I had no idea my car could corner like that. Thanks also to Howard Yao for showing me how it should be done.

My question is about some bad stumbling and loss of power that my stock 74 2.0 had. It seemed to be bought on by the really sharp corners. Particularly the 270º loop arround.

I would put my foot down comming out the turn and the car would be all jerky. It felt alot like the problem that I have had before with the TPS at highway speeds. But that was cleaned recently.

Has anyone had this problem before?

I had a 3/4 full tank of gass.

I would like to get it fixed as I intend to go auto cross agian now.

could be a lot of things, but if i recall right, your car was puffing smoke when it happened too.

i'd say, check your head temperature sensor!

it might have come loose or the wire is loose or brittle.
i have seen this exact same thing before (at an AX) ...

Sir Andy

You said I have smoke. I did not know. It may be I had too much oil in there! I over filled it accidenlty. Could to much oil be sloshing arround then getting up into places where it should not? Making me blow smoke and loose power.

I'll try draining it tonight and drive some hard corners tomorow to see if it helps.

About half a quart over full should not hurt anything, and is in fact recommended for autoX. It helps keep the oil pickup submerged just a little bit longer in the longer sweeping turns.

no, oil overfill and loss of power are usually not related ...

if the CHT is loose the car will puff smoke every time you're loosing power cause the FI will pump loads of fuel into the heads and when it catches again, it'll spit it out the exhaust.

while you're in there -- check ALL electrical connections -- especially grounds. take each off, clean it with electrical cleaner, put back on.

doing this methodically, i found a bad connection to one of my fuel injectors -- the wire was barely coming out under hard left cornering, causing the car to stumble until it straightened back out. strange but troooo.

good luck
