Most engines run hydraulic tappets. Thes bleed down and allow a tappet problem when started until oil pressure buils up and takes up the slack. Comes from incorrect oil filter that doe's have a nonreturn valve in it ( el cheapo) low oil pressure , incorrect grade of oil and worh hydraulic lifters/ tappets. Some you can do but the lifters will have to tested for bleed down time at a dealer

I have a corsa utility 2004. Starts fine and once warmed up will cut out. will battle to start again and backfires sometimes. Once started it goes well with out further problems until the next day.


I would replace the spark plugs . Hmm, backfiring is usually a fault in the spark, bad plug wire or coil. Intermittent missing is tough to find unless you test the wires when it starts acting up by putting another plug into the cap and grounding it, have someone turn the engine over to see it's nice blue spark. Ignition modules will cause same problem when they go bad, check for bad or shorted wires to ignition .

Multiple problems with Hyundai Sonata : 1. Car does not start very often. 2. When it does I have an orange light on the dash showing a car with skid marks. 3.The shifter gets stuck in park sometimes.


on your a/c blowing warm air at stops it sounds like radaitor cooling fan not working, fan motor or fan relay most likly cause, light with skid marks sounds like anti=lock brake system problem, possible bad wheel speed sensor, on shifter getting stuck and engine not starting sounds like ignition switch going bad, hope this helps ?

Idle is high at start - 1800 rpm. Seems like excessive white smoke from exhaust. Put into reverse and back out of driveway it has a regular shudder (bump bump bump) but not hard metal grinding sound.....


white smoke out of the exhaust would be a sign that it is burning coolant... if it goes away after it warms up, it could just be condensation inside the exhaust pipe. 1800 rpm is a very high idle, maybe have your IAC motor on the throttle body checked... check engine light? if so have the code read at your local auto zone.

Once car warms up it begins to miss, as soon as i take my foot off the gas it dies and will not start it turns over but wont fire. now once the car cools down it starts and runs fine until it warms up...


sounds like a typical ignition coil break down. when they go bad they act up when they get hot. very easy to replace. it is what the plug wires come from.

Sounds like vapor lock. In laymans terms the engine heat causes the fuel flow to stop. Once everything cools off the truck starts. Insulating around the fuel line seems to be the solution. Try aluminum foil. Or perhaps a reroute of the fuel line to get it away from direct engine heat.

Transmission dosnt shift when truck warms up


FYI
I have a 1995 GMC 1500 with 5.7 truck that the ABS Light comes on and then the tranny starts jumping gears and speedo goes crazy- Changed ignition switch and that did not help.
You said that you had changed the speed sensor on the tranny and that did not help ?? If so that was my next step. Let me know if you find and answer and I will do likewise.
