my celebrity runs very rough when it has reached operating temp, then turned off for a short period of time, it starts up idleing rough and eratic until engine is raced then it seems to clear up. it starts up with NO problem when its cold ( not ran overnight) A mechanic ruled out the computer is not putting out a rpm signal, he replaced with new one and no change he also replaced crankshaft sensor, I have replaced coolanttemp, oxygen, map , tps sensors and no improvement, all this is costing me more than what the car is worth but I cannot afford to buy another car at this point, any ideas would be a big help, Thanks ....John

 

could my coil packs or ignition module be going bad??

 

+1

 

+1 ?? meaning? I am going to replace both the control module and the 3 coils, I ordered the generic brand which was cheaper, will it run any better??

 

+1 means I agree with that statement
It will only run better if thats what is causing the problem

 

well funny thing happened that convined me it is the ignition module , I disconnected the 3 harness connections one night, then next day I cleaned the contacts ( they weren't really dirty ) and reconnected them and car ran better for a day or 2, I don't understand why but I read that same thing happened to someone else wrote in a simular formum,Does this make any sense? the 3 connections were all tight and not corroded at all.

 

well now i'm thinking my Eprom may be bad so I ordered a stock one for my specific ecm, so I have question , what should I try first or should I say if my ICM is bad will it kill the new EPROM and vise versa? so Should I install both the new parts at same time, or is there a risk of one damaging another? (possiblby bad ICM with new EPROM or new ICM with possibly bad EPROM) another reason I got a new Eprom is because I'm not sure if former owner did a speed densidy conversion and didn't put any id or stickers saying it was done, I assume it was converted because The maf relay had been removed and when My mechanic scanned my ecm , he got eratic readings which is descriibed in a article I read on a speed densidy conversion. so with stock EPROM the system would use the maf and its relay, and also a stock IAC which I have bought already. This car has me confused but I think I'm on the right track, I hope

 

Anybody got any thoughts on all this?

 

Thankfully, the Hills honey didn't have to worry about any stalkers last night when she dined at the West Hollywood eatery, though she might have gained a few more admirers after parading around in this scorching hot getup!
