i got a 99 withthe sohc engine, when i start up the car the engine revs up and makes a loud rattling sound, then it comes back down to idle speed and just makes a ticking sound. It also starts rattling at about 2400 rpm it sounds like it might still be making the noise at higher engine speeds but it is hard to hear over the regular engine noises and tire noise. Anyone know what could be causing this? Is it serious? Also i have been having trouble tryin to get my car started when its cold. I would turn the key and the engine would start then die immediatly after i returnthe key to the on position. It continues to die after repeated attempts unless i step on the gas pedal and give it some gas. then it will start up fine so long as i rev the engine a little bit. As of yesterday i tried starting my X up and it would just die like before. i tired giving it a little gas to start er up but this time the engine died as soon as i took my foot off the gas pedal. I tried starting it a few times using the same method as before but the engine kept dyin as my foot came off the gas. i then started the car up by givin it some gas and reved the engine a few times and then tried to maintain idle speed by giving it a little gas....did this for bout 5 mins then i took my foot of the gas andthe engine died. I really wanted to get my car started cause my jetski was on the trailer onthe back and i was really lookin forward to a day of jetskin. so being desperate i put the car in nuetral and started it up and kept my foot on the gas as i shifted into drive and then drove off. after about 1 min of driving down my street i took my foot of the gas and the engine stayed running. i took the car down to the boat ramp and left it there over night. this morning i went to go pick up my car and it started just fine. IM not sure if these two problems are related but they both are annoying...any help would be greatly appreciated
