Question Asked: 

my 2003 jeep liberty sport 3.7/5 speed check engine light gave a P1281 code(not in Haynes manual) apparently its a manufactures code for a coolant problem. says that engine not reaching proper operating temp usually due to thermostat sticking open constantly letting coolant flow. there for cat converter not getting hot enough making it run rich and get poor mpg. New thermostat has less than 500 miles on it since engine has been completely, professionally rebuilt from top to bottom and water pump was done. temp gauge shows half and if I leave it running for a few mins cooling fan kicks on do these two things mean the engine is reaching operating temp? and this could be something different? Im about to change oil and flush radiatior after break in period of 500 miles should I just change thermostat and see if light goes off? engine runs fine except the check engine light and mpg I just did all 4 o2 sensors per prior check engine light (it went off and mpg got better) then light came back on and gave this code.

Question Asked: 

when setting the timing on a 1989 camero rs 2.8 V6 MPFI using a timing light.(after disconnecting the EST) Is the notch on the harmonic balancer the actual TDC or is it the white line just to the right of the notch? Haynes manual says to line it up to the notch but the white line looks like it is factory painted. Its a 2 degree difference depending on which one is used. Also do u know the factory setting for that engine the VECI label (under the hood) says 10 degrees BTDC mechanics on some camero websites are saying factory setting for this engine is 6 degrees? just wanted to get your thoughts on this thanks for your help.

Question Asked: 

recently bought a 1989 camero RS that had been sitting for a year or so. Had quite the time getting it running but with some help from u guys I finally did yeeeeeey :-)thank u for the advise it was very helpful and it runs very well now. but now I have moved to the brakes. Calipers were locked up on rotors and caliper pistons locked up as well. Got them off and got new calipers and pads for front, rear drum brakes seem to work ok. blead the rears fine but cant get any bleed out of either front brake about to check lines after it stops raining other than that what else could cause this problem? if the rear work booster should be ok right? don't know to much about brakes lol any ideas will help thanks.

recently bought a 1989 camero rs 2.8 MPFI that had sat for 1 yr but ran before that. it cranked but wouldn't start (started with carb cleaner spray but would immeditly die)fuel pump didn't run checked relays,fuses ect. changed out FP,new plugs (still nothing) was giving me a MAF code got new MAF sensor and relay ,code went away but still not starting.

Question Asked: 

my ? is actually about a 1989 camero RS coupe with a 6 cyl. 2.8 car was sitting for a year but ran fine before that starts when carb cleaner is sprayed in air intake but dies out. I didn't hear fuel pump running checked fuses, rely and elec. curcit all fine changed out fuel pump which is now pumping fuel but I broke the ventilator valve assembly/fuel tank vent valve (Haynes book calls it ventilator valve assembly)(looks like a little canister with only one end attached to a hose)cant find the part anywhere they say its discontinued. Would this keep the car from running/starting? will engine run without it?
