so i got my exhaust leak fixed its still ideling around 600rpm in reverse and drive about 1000 in park. yesterday i took it out warm and it was poping and bucking while i was in drive with my foot on the brake and not moving. today no problems like that. when i accelarate the things ticks and vibrates loud and when i hit a certain rpm my car shake slike crazy i think the motor is gonna fall out any ideas what can be wrong i changed the ignition module full tune up and a mas air flow i had no problems like this till i jacked up my motor and replaced my oil pump which i still have low oil pressure only at a stop in gear other wise my pressure is normally 50-60 psi when i acclerate. comes down to about 10 psi just before red when i idle at a light.

 

sounds like a rod bearing...except that mine made a knocking and vibration,but urs just might not be that bad yet...wait,did u say u did a full tune-up on it? if so,r u sure the timing is right,b/c if the timing is way off it could cause it to do that

 

hey thanks man i had 2 cyliders cross fired there fore i was driving with a miss. but now she purs beautifully. another question i have is i just yesterday bypassed my coolant so it dosent go threw the throttle body anymore and heres my question my fans used to kick on at 225 and pull the temperature down to about 180 or so now the fan kicks on about 240 just before overheating and pulls it down to 220 when im driving it runs so cool. tonight while idling in trrafic my fan at one time did kick on at about the norm of 225 and when i got home i tested it again it kicks on again at 240 im ordering a new temperature sensor and plug from jegs shortly what could be doing this.

 

You may have air pockets in your coolant system. When you fill it with coolant, you need to crank it up with the radiator cap off and let the water pump circulate the coolant through the engine. Let it run till the thermostat opens and keep it topped up, then check it after a couple days.

 

ive tryed that i let it run till about 240 it didnt drop down a bit i turned it off and it dropped down i filled up and have been checking it for 3 days and its completley full
