OK so I just replaced the Timing Belt and water pump on my 95 sohc. it ran great...till it got cold...and now it takes about 5 minutes of cranking to get it to start, then i have to punch the gas a couple of times to get it to run right. then it's fine.

i hooked up a scanner to it. itthrows a temp sensor code in both standard check engine codes as well as obdII codes. this i know is broken, just haven't replaced it yet.


Any ideas?
Q

 

it sounds like the timing is slightly off

 

How could the timing be off?

I lined everything up to top dead center, and it's all computer controlled right?

 

I belive, you need to back the cam off half a tooth so when you put the belt back on and release the tentioner it will pull it to tdc. according to my service manual it says....

set the crankshaft sprocket to tdc by aligning the sproket wit hteh arrow on the oil pump housing, then back off 3 notches before tdc set the camshaft timing mark by aligning the timing marks. rotate the crankshaft 1/2 tooth counterclockwise from tdc. install the timing belt in this direction. starting at the crankshaft go around the water pump sprocket, idler pulley,camshaft sprockets and then around the tensioner pully. move the crankshaft sprocket to tdc to take up the belt slack. install the tensioner to the block but do not tighten the fasteners yet. use a torque wrenchon the tensioner pully appy 21 ft. lbs or torque to the tensioner. with torque being applied to the tensioner pully move the tensioner up against the tensioner pully bracket and tighten the fasteners to 23 ft. lbs. pull the tensioner plunger pin. the pretension is correct when the pin can be removed and installed freely. rotate the crankshaft 2 revolutions and check the alignment of the timing marks.

hopefully that helps

 

Does anyone know...

If I hook it up to scanner..what the timing degree's should be?

It'll tell me.....

Then I'll know if I need to make an adjustment.

 

Also..why would this change from warm weather to cold weather?

it started fine when it was warm...just started aving problems when the eather droped sub 40 degrees...

 

a scanner wont tell you what the timing is set at.....spark timing maybe, but not the valve timing

there are a few different posibilities
timing may have jumped a tooth
if the temp sensor isnt working properly then there is a possibility that the car may have overheated and caused a problem with the headgasket, making it leak and not have the proper compression
