lately my temp gauge is acting a wierd....needle keeps jumping from normal to cold then normal. this only happends when the engine has fully warmed up and crusing the streets

i had a code pulled and it said something about coolant temp sensor..but this was a cheap autozone code reader...i have a friend with the real tool i will recheck all the codes later on tomorrow or this weekend.

sometimes i would get in a hurry to one location and another and would shut the engine off right away then when i come back out to start it, it would not start...it'll keep cranking for a good 5-10 seconds before it actually starts, and when it does it would idle between 2000-2500rpm. i give it a little gas and the throttle would get stuck then rpm slowly drops down. obviously the car would run like ****....then the next day it would start normal and drive normal. could there possibly be a vac leak? check engine light likes to turn off and on a lot of times too...

any help would greatly be appreciated.

 

Replace your coolant sensor with a green top one. May sensors (black top) were defective.

Turn your car on, wait till it says "ok" then start/crank the engine over. I don't think your letting your fuel pump prime.

 

i am in the process of installing the ECT sensor!! i bought the sensor from TT-stuff.com and i cant figure out if i got the right sensor or not!

 

You shouldnt have any problems both work fine. I had the blue and used a green one.
Im sure that by the time you read this your problems will be solved.
