So i was driving home from a RX meet and my car about 4krmps with just 1/2 powering gives a little back fire pop and it feels like the rotor spinning but theres no gas going into the motor. i know my fcd and air sense saved my motors life. so i clutch and hit 3rd and just sit there at like 2500rpms and cry for a sec and then give it some gas and between 3500 and 4k in 3ed it dose it again so i drive the rest of the way home under 3k rpms and at about 1/4 power. and theres a slight vibrating sound in 3ed gear when gassing it about 3500rpms. so now I'm really realy scared.

also when i stared it the leave my house and the coolet light came on so i added water and when i reved over 1500 to warm up a nasty sound like a fan belt with oil on it but it wasn't the fan belt. and had some white smoke in the motor bay that when i popped the hood but it was very little and didn't happen again.

 

alot of times these cars get a 3800 rpm hesitation, where it will kinda like hesitate or cut out for a second at that rpm, it is ussually due to poor grounds..

how much psi of boost are you running and what fuel mods do you have??

dont run more than like 7-8 psi on the stock ecu or your asking for trouble

 

Check compression.

 

i listed all mods and running stock or at lest the manual controller is set to stoke


95psi/95psi yesterday

 

just drove home from work, 3ed didn't do it in less i downshifted to 3ed and floored it and it did a little hesitation at 5krpms and still at 4th but not as violent. but the slight sound of something squeaking was still there.

 

Could it have advanced it's own timing too much..? Once my Rex did something similar and it was the CAS has "jumped" time a little bit...... Just a thought.
