Help...I screwed up!

[Davey G]

I cleaned the engine department of the 280Z last night, trying to get some of the dust off from the final paint sanding. But afterwards, though it still starts fine, it won't get past 2500 rpm, and just cuts off at that point. I popped the dist cap off and saw no water, but left it off overnight, just to let everything dry out. But still this morning its cutting out above 2500 rpm. What did I do? What do I check?

Water. TPS.

tps????

Throttle Position Sensor.

Things tend not to dry-out during the night. Have another go this afternoon.

Where is the TPS located? I looked on the EFI sticky thread, but the diagram did not list it.

Locate your throttle butterfly, it will be at the front if your engine's air intake collector and will be the last part in line joined by the throttle linkage. The TPS will be screwed or riveted onto the side of that throttle butterfly housing, probably a lil black box and it will have a wire connection going from it.

Look for puddled water in various parts of your car's engine bay and on/around the engine itself, and take care of them. Generally it's never a good idea to spray water directly into the engine bay becuz of sensitivity issues you're now dealing with. If you still have the problem, open the hood and get hte engine bay in the sun for a few hours to let everything dry out.

It looks like this ....

Unplug the connector, use compressed air to blow out any moisture in both the connectoor & the TPS itself. The connector boot is probably cracked and let the water in. Very common problem.

Thanks. I'll post whether this remedies the problem. -dg

Yep, TPS had water in the connector. I took some canned air, like we clean our keyboards with, and blew it out. Not a problem after that. Thanks for the help guys! You guys are awesome (and save me money). -dg
