HELP

aparently you have a coolant temp sensor problem,check if they are conected. they should be on the thermostat housing,those wires are prone to breaking. also check your timing and verify that your timing belt marks are set correctly.

by the way ,timing should be set at 10 degrees btc ..

here are the links on the code you have and also how to set the timing..

Mine ran really bad and wouldn't idle either for the coolant temp sensor disconnected. I dont know why they designed it like that but they did. Fix the connection and you should be fine.

so just the wire broke ans not the actual sensor at 1st ithoguht my sensor had gone out and i got one off one of my parts motors but it donset fit my wireing harness i was just going ot change thme out but since the plug connectors r different i dont no i guess i will check trhe wires and make sure they r still good and if they r thne i will have to go get a sensor that will fit my harness
