Hi all,
thanks to everyone who's contributed to this site. It's been super helpful.
89 sidekick 1.6L 2dr 4x4 A/T
CEL on with Key, off when started. Code 12 when codes pulled.
Vehicle warms up to 180+
Cold start 2000 rpm
Idle drops 500 within 30 sec to 1500 rpm
When warm 800 +- 50 rpm
Load on 950 rpm
Compression 170-175 psi across all cylinders.
New parts
TB all gaskets.
Air filter
Timing belt
Water pump
Plugs
Wires
Coil
Distributor and rotor
O2 sensor
ECT
Oil pressure sensor
Complete exhaust (except manifold)
Vacuum modulator
First let me say that my rpm isnt completely stable. It fluctuates up and down +- 50 rpm at all times. Using the propane technique I've discovered if I apply propane to back side of EGR (where you push for stall test) the idle increases. I assume this is suppose to be air tight? No other areas see any rpm change with propane applied.
Second issue is, when I put into gear the rpm drops 200-400 rpm and will not recover. With any electrical load (headlights, heater) the rpm increases about 150 rpm.
I was willing to live with these issues until a few road trips have shown I'm getting 18 mpg highway. Other things to consider is I'm running a 2 inch lift with 31's. With stock gearing. From what others have posted this seems to be horrible mpg.
Anyone have any input? Thanks
