Recently had my motor replaced in my cavy. Its an 01 Z-24. Had a replacement from LKQ put in. At first it ran fine for a few days but then it started to runb really hard and misfire. usually this was accompanied by white smoke and you could smell the gas in the exhaust. So i replaced the spark plugs and that helped. Ran fine again but then it started doing the same thing again off and on. Happened in starting, idle, prolly woulda been like that if i drove it but i didnt want to. I would shut the engine off and turn it back on and it would correct itself and run the way it should. then while driving down the highway it would seem to bogg down on the motor and the traction control light would come on noting that it was off, and if i would accelerate up a hill or throttle up the motor to about 3500 the temp gauge goes from normal operating temp to zero. needing some direction. Just want my baby runnin again. Love the car and dont wanna give it up.

Hi,
Sorry about your troubles. Obviously you hired someone to put the engine in, they are responsible for it running properly. Take it back to them and have them fix it.
Question though, why did you put in a new motor? Was there an issue you were trying to fix and if so what was it? A bad engine burning oil and water can sometimes clog up the cat and once clogged there is a lot of back pressure which prevents the motor from breathing properly and the car will behave like you indicate it does. Run fine early, then slowly run worse. When you shut it off the pressure in the exhaust from the cylinder to the cat is allowed to bleed out and the car car once again breath until the pressure once again builds up. IF this is the problem, it isn't the mechanics fault and prepare to pay a pretty penny for a replacement.
Could be an electrical engine control item as well but diagnosis is needed.
The electrical operation of the gauges tends to indicate a bad connection somewhere, most likely a ground wire which would do all sorts of strange things to your car on so many fronts. A fire could be a result as everything that depends upon a given ground wire tries to ground through a wire that is woefully undersized to handle the current now demanded that it handle as a result of another properly sized wire being disconnected.

Let the car sit for awhile and then drove it again. No problems...untill about 2 weeks later started having the same problems again. Trac off light was on engine was idle was going from 800rpm-1300rpm in no particular pattern. when the motor was down about 1000rpm i tried to drive back home and when i shifted from park to drive it went into drive really hard and acted like the trans had a load on it. someone thought it might have been the IAT sensor. just stumped to what it can be......

if it is a cat issue what can i do to determine that?

Check the ground wires to the block at the front of the engine above the starter. I replaced my engine because a rod went through the block in October and it ran similar. If the block isn't grounded properly then there's no path for the spark from the plugs to go and I'm not sure if the temp sensor grounds through that path either. But what happened at highway speeds there was enough wind and vibration to move the ground from touching the stud it bolted to and my car would run like crap until I stopped. Seriously, I thought I had bought a junk engine.

so i just had started my car up today and it just recently rained the night before. started headin to show a buddy of mine my hunting bow and about 5 miles outta town my temp gauge was going up and then just flatlined to nothing. and my trac light was on also with a check engine light. so i decided to stop and have my buddy run to see if it was throwing any codes, sure enough before i get there the check engine light goes off soo im like wtf...but the temp gauge is still zero and trac off light is still on and he pulled a code about the coolant sensor. dont remember exactly what all it was but if i remember it was the coolant sensor or the ets. about 5 minutes later the trac light went off. if the coolant sensor was bad my fan wouldnt kick on would it? cuz my radiator fan was runnin fine. so could this be a computer problem or ground problem?

i dident read through all of your posts.. but it sounds like the coil packs .. thats what mine was doing.. car dident accelerate at all . sounded like a subaru and smelled like pure gas

well right now my check engine light is on along with my trac off light....cant figure out what the *(#$ is going on. Tried to find a bad ground but havent found one yet......so i dunno what to do. like i said in last post ran to see what codes were pullin and all i got was about the coolant sensor. but all my fluids are good
