1) Check for ignition problem. If you have a distributor, pay special attention to distibutar pickup and also ignition wires.
2) Check the TPS. Voltage should change smoothly as you move the throttle.
Yes , although you will have to top up the engine oil level ( or prefill the new engine oil filter ) * assuming you haven't put the required amount of oil in the engine already *
check that the O ring was replaced when oil filter was changed. id O ring is good and filter is tight, and housing still leaking, replace filter housing
Some air purifiers do require a filter to be changed others have a filter that can be cleaned.
Spark plugs, distributor cap, and distributor rotor should be replaced. Ignition coil should be checked for corrosion at the post. Clean or replace as needed. Spark plug wires should be inspected for corrosion. Clean or replace as needed. PCV valve should be cleaned. Fuel filter should be relaced. Air filter should be inspected and replaced if needed. Oil and filter should be changed if applicable.
Pre-filter for what? You posted this question in the Fuel Filter category. So I must assume you mean the pre-filter on the fuel pump. That is changed when the fuel pump is replaced.
If the diesel fuel "gels" then yes the filter will need replaced.
The oil on a 2008 Audi Q7 is changed by placing a drain pan under the engine and removing the drain plug. The oil filter is then unscrewed, a new filter installed, drain plug replaced, and the oil filled from the top of the engine.
I had the same thing happen after Jiffy Lube changed the air filter. They forgot to plug the vacuum line back into the back of the air filter housing.
yes and no did not changed fuel filter
Check to see if it getting spark/fuel Check rotor
ignition module
If you mean that you changed oil , then RAN THE ENGINE with the old oil filter installed , then changed the oil filter , you just mixed the dirty oil in the old engine oil filter with the new oil that was just put in . So , not the best thing to do
