Question about 2005 Chevrolet Express

Open Question

2005 chev express 1500 cargo. 4.3 liter V6 100k miles Problem: engine rev's stay high as it moves thru the AT gears (used to smooth out and not have the high rev sound) Feels a little more sluggish than prior to issue, just started 4-4-11. Background: 'check engine' light was on from 4-2 to 4-3 then went off. the only thing i did was check the gas cap and fill the tank. vehicle start/stop cycles since issue = about 4 and counting. thanks for any idea's you have.

SOURCE: Check engine light/gas cap will not stay tight.

yes the gas cap could cause this,also check evap. purge solenoid and hoses for cracks or kinks,the solenoid is on the inner fender and has 2 hoses, one to the intake and one to the canister, the most common cause of this code is a defective purge solenoid.

Sounds like sway bars may be too light for the load in the van. I don't know your specs for this but may have to get heavier set and put on both front and rear to help stabilize. If you have some racing buddies they can explain...

there is a large evaporative leak. keep away form ottozoo, they dont have the brain power to actually diagnose a light bulb., their job is to sell parts., if they sell you the wrong parts tough.Take it to a qualified repair shop that does a lot of GM work or the dealer.

Why does my 2005 dodge ram 1500 3.7 liter only goes up to 4000 rpm when i reve it up and it starts to sputter when in park?


its the rev limiter. its suppose to do that when the engine has no load or the vehicle is stationary so you don't break the engine. now when your moving and it happens check fuel filter, fuel pump, air filter,etc.

Fuel Grade for 1925 Chev.4


Octane is a measure of how smoothly the feul burns, You can never have too much octane. The reason you get more power from high octane is because it burns fractionally slower, allowing more pressure time to push the piston. Low -er octane has more tendency to explode (in pockets) versus smooth burning, resulting in popping or pinging, more unburned fuel comming out the exhaust, and potential damge to piston or valves. So I did not actually answer the question, but hope I helped. Use a little mid grade and listen to the engine under power, (rev engine), for pinging or popping. If it sounds smooth, you should be good. If not, upgrade.

Timing spec. 1998 chev 1500 pickup with a 5.7 liter


you need a scan tool to check the timing. You can get close by getting the #1 piston at top dead center, and then dropping the distributor back in, making sure it lines up with the oil pump shaft. then rotate the distributor back and for untill it runs smooth. again this will only get you close. you will still want to have a mech. check with a scan tool.
