Dont you hate it when your cars sick??

I certainly do & I bet a lot of you guys are the same. Spent 2 nights searching for info & so far 2 days bending over the car checking & taking things apart. No wonder I"ve got a headache & backache but cant sleep till she"s fixed.

There are dozens of permutations of what it could be so I will spare you all the detail & for now ask a couple of specific questions to help me onwards & hopefully lay some fears to rest.

Its a 94 n/a auto thats (now) idling at 1800 rpm when hot & misfiring with mil & red warning lights on but showing no error codes (mil light on continuously during code check).Mil warning started doing this intermitently for a few seconds after start up 2 weeks ago then cleared to run perfectly ok but last Sunday it didnt resolve itself & got worse so can only pull away in 1st gear. Seems like in D it is pulling away in top gear to little avail.

1st Q... how do I check the signal/supply to the idle control valve (valve works off car when voltage applied but I think its not adjusting on warm up on the car hence rich idling).

2nd Q... would the auto box play up if something wrong with the fueling or whatever engine/sensor faults may be confusing the ECU ? I"m hoping if the engine prob is sorted then the gear box will return to normal. ( just like I will )

 

Any experience/knowledge on these 2 points would be much appreciated .

thanks , Glenn.
