Ok was doing Pre-winter Prep today and found a broken vaccum Line I do Believe
was wanting to ask your Opinion ...also wanted to ask where the hell the ECT is on this thing





The truck has been running fine...but I have noticed a drop in my gas mileage lately and couldnt place it..plus the truck doesnt heat up worth a hoot..so someone answering these questions would greatly help me
Thanks guys
Dustin!

 

whats an ECT?

btw that looks like a vac line, see if there is enough hose there to just slide it back on.

 

oh not ect Engine Coolant Temp sensor ....Dunno how the Abrieviate it lol

 

thats the Vac line that goes to your purge system......

 

Look around near the thermostat housing. It should have 2 wires, one gray/red and the other either gray or light green/red.

 

Pull the live data with a scanner and see how the computer is correcting your fuel trims. If there is more than 10% correction it is running to lean due to a vacuum leak. STFT's should tell you this.

 

What sort of Live data scanner do I need? I dont own one..and all advanced can do is tell me if its throwing codes...which I dont know...my cel is burnt out has been for a very long time...
The motors got new o2's new air filter fresh oil fresh tune up...thats sorta stuff
its a 95 2.3l it IS obd2
The truck runs cold..and smells rich...I just found the one vaccum line today
Truck has new thermostat
thats why my next guess was a temp sensor

Also is there any way to test the temp sensor to see if its working properly or reading properly?

 

I have an innova scanner. It was 240$ with tax from Murrays auto parts. Autozone sells something similar that will check live data. I don't know if there are the same live data capabilities on a 1995.

 

Thanks for the help
Fixed the Vac Leak
reset the puter
and had Advanced check the codes
Didnt show any codes so yeah
I am seriously considering getting a tunner though for the live data reading/ tweaking in the future

I know scan guage works on the 95 borrowed Robert99's at a meet one day
So I'd assume most of the life data recording stuff would work!

 

Whenever you clear a code on an obd2 computer it automatically throws a p1000 code. If the engine is running lean and the short term fuel trims are positive to compensate for the unmetered air the p1000 will turn into a p0171/p0174.

I had a really good post for this style of problem but the mods never stickied it.
