I need to smog my truck in California and I have to incomplete monitors. 1 is Evap and the other is secondary air. I can't figure out what my issue's are.

It still has a slight leak. What else could be the problem?

The other day on my way home it just feel off/lost power. Today it was hard starting, sound like it was flooding of starving for fuel. Made a quick trip, then went to make another and it started ran for about 30 feet (poorly) and died. Wouldn't start for a while, then 30 minutes later started it and put back in the garage. About an hour of watching utube videos I went out and it started up, still sounded like it was loading up, but if I accelerated very slowly I could get it to 3000 rpms but if I tried to accelerate faster it would sound like it was loading up again.

The parts store sold me 75 90 weight oil but no additives. Im told I need 80 90 and the additives. Is this so

coming off the freeway, into town a mile or two, make a turn and it dies. while turning i press the gas, instrument panel lights up with loss of power. After coasting to a stop. No crank. Pulled off both belts, no crank. buy new starter no crank. disconnect battery to try any reset no crank. park break off, trans in neutral tried to turn crank shaft clockwise, no turn, even with breaker bar. any more good ideas? next up is pull spark plugs and try and turn crank shaft again.

Are They hard to change out? How much is the cost for one?

Ruled out engine, no oil pressure change. My dad raised the tail of tranny near u-joint to remove pan. Could this be cause of knocking I have noticed recently? Knocks all gears, louder in park or neutral.

I see some fluids by my radiator and windshield washer tank

With the A/C on driving along, occasionally, the heat starts blowing out the driver side vents. Turning engine off and back on again resets the door. Maybe related: just replaced the fan relay connector so the fan would work again. Black wire (out of the seven in the connector) was overheated. This heat/A/C thing was happening before the fan quit though so its probably not related to the connector.

door window passenger side will not go down

I can turn off truck and restart engine after a half minute and it will come on for a few minutes again then it goes out again. Works fine at night (dark time) but daytime I have this problem. Have relaced blend door actuator. Codes: PO466,P0455,P0300 Bought new gas cap, plugs and wires. Haven't reset check engine light yet. But light did go out for about a week then came back on. Anyone have an idea?

2005 gmc sierra sle z71 1500 is stuck in 4lo. I have change out all parts I can think of. I have took the transfer case motor off and change it. Can't get it back on till I get the new motor in 4 lo. Silly me. My fault on that. Change out the switch on the dash, the modular under the fuse box and the actuator. Battery had been disconnected and reconnected. Anything I am missing? Does it need to be reprogrammed?
Any help and help will be appreciated. Thanks.

My horn stops working one day then starts again the next and so forth. Im trying to figure out the problem. I checked the fuse and the fuse is fine. Im not sure where exactly the horn relay is located and I also believe I only have the one horn on my model(drivers side under headlight) because when I activate the locking alarm it makes the same pitch sound as my actual horn. Not high or low. Maybe the line is corroded due to rain or maybe its a bad connection or have gotten some water on the horn. Any ideas on how to fix the problem? Also I'm looking for the horn relay so I can check it. Its not in the under hood fuse box with the other fuses so maybe they put the relays somewhere else?

air doesnot blow out of the vents on the dashboard only blows out of the vents on the side of the dash board and the console. its cold though.i want to know why it is not coming out of the dashboard,

Second set of disc brakes since I have owned this truck. I have replaced everything from the hub out on both sides: rotor, caliper, and brake pads. I still get lots of noisy clanking from the front brakes when under way,especially if I hit a bump or hole in the road. A little pressure on the brake pedal and "wa-la" no noise...???????
