I have a 91 with 190k on it. i am having an issue with it bogging down around 2500 to 3500 rpm then it will pick up and blast off fine. It doesn't do it all the time but it is more frequent lately. When it happens the exhaust note will change as I apply more throttle it doesn't really pick up speed then suddenly at 4000 rpm its like normal. After maybe an hr of this it will throw the CEL and its all good. i have new coils, plugs and clean throttle body. I have removed the clock fuse to clear any old codes but couldn't get it turn the CEL back on during a 100 mile trip even though it was doing the same thing after about 50 miles.
I have tried the search but it's kinda wordy to but into the search in way to sort the results. i think this problem is somewhat common and sometimes directed to water in the plug /coil pack but I am sure this is not the case. I still have the original o2 sensors and injectors on the car. If anyone has any suggestions until I can get a code out of it would help.
