I have a 89' irocz 305 TPI..The car runs like a champ when started cold but as soon as it warms up (1-2 minutes) the engine sounds like its choking...I can hear a constant clicking noise where the EGR and FPR is but I cant quiet distinguish where it is coming from exactly.
Also while driving if I stay at a constant speed sometimes the car starts to bog out (usually at 25mph and 35mph) like its missing, but as soon as I give it a little gas it goes away (it does return though). Any ideas or suggestions thrown at me i will gladly take into play! This has been happening for months now. I am using 92 gas from chevron, also using lucas fuel injector cleaners on my last 2 fillups.

I am looking forward to changing my EGR and FPR valves hoping to solve this issue. But if this is not the problem then I'd rather save myself the hassle....If anyone from past experiences could post their 2 cents, I am pulling my hair out on this one....

 

Sorry guys as you can tell I am pretty amateur when it comes to car stuff! haha but I have Ohm'd out my fuel injectors and discovered that 2 of them were BAD!! so that clicking noise I was hearing by the EGR was the injectors... Just thought I would let everyone know...
