hey guys. my 1991 legacy rs pretty much has a hard time to start everytime i go to start it, hot or cold it takes about 5 seconds of constint winding to start. i did get a tps code but i dont think it has anything to do with it. i did change the injectors not long ago but a good couple of days after changing them it started without a problem. then it just started to get hard to start.
any ideas? thanks in advance.

 

Possibly the coolant temp sensor. Think mine needs doing, starts first time but revs really low for about 4 seconds before it picks up.

 

doesnt really rev low tho. and wouldnt that throw a code
