Hi guys

 

My car is idling very roughly and engine also not running smoothly. The Power is definately there as the car still moves but just not smoothly.

 

The previous engine blew so I replaced it with a recon motor.

 

Any help on what to start doing first to locate the problem??

 

Thanks

Have you looked at the workshop manual? Shows what to look for for different symptoms such as rough idling, etc. You'll need to narrow it down according to the things in the manual.

 

- The temperature sensor on the front pipe from the rad is a good cheap fix that often helps rough running problems

 

- There's a valve that controls extra air for when the car is idling

 

- Check you are firing on all six cylinders by removing the coil pack connectors. Each time you remove one you should notice the change in engine note. If not then that one isn't doing anything.

 

- Check for sparks on the plugs

 

- Compression? although if its a new engine that should be ok

 

There's a whole list of things in the manual.

 

Seeing as you've replaced the engine and still have problems then it could be the wiring loom is cooked and connectors need cleaning/replacing and maybe wiring needs looking at.

Try the MAF or AFM. Mine was running crap till I replaceed it.

Cost Between £140 and £180.
