Opti headache!
So my 94 camaro quit running due to a bad opti, I had a shop replace it with a cheap cardone unit that I got for 220. (I know your supposed to use ac delco or msd but I'm leaving in less then 2 weeks for the marines so I just needed something cheap to slap on for a week or so) after they replaced it the car would start and idles, however it idles very rough and smells rich, also will not rev at all. The shop believes the timing is way off cuz the cheap part I bought is ****, broken or both. Just wanted to get more opinions or info on the mater. Fuel pump is good coil and Icm are brad new

Sounds like the opti. When mines got drenched in coolant mines did the same..

If its a pin drive, you can't screw it up. If you do you would break the opti. They're splined with a double spline to locate it in the proper position. But it does sound like there's something amiss. If you had a shop donut, taken it back and make them fix it. They should have a warranty on labor and the part has a warranty as well.

Ok, so I took the car home and replaced it myself, I swapped the opti for a brand new one because it was under warenty. I put the opti on correctly! I did not force it on I made sure it mated flush with the block with very minimal pushing. I know this cuz I had to take it off and spin the pin a little then try again like 6 times. I made sure it was on correctly. After I put every thing back together this morning and tried to fire her up, she ran the exact same way! Idels rough bogs down when I try to rev it and sounds/smells like crap! I am starting to wonder if it's the OPTi at al., I have a sneaky suspicion that it might be getting a weak spark due to a back coil wire. Because it's kind of weird that it did it for two brand-new OPTi sparks a row. It may be just a junk brand idk, but the coil wire has not been replaced since I've owned the car and it was falling apart when I tried to put it back on

Replace the coil wire then check the fuel pressure with a gauge

Awesome ....just curious, you get the Summit brand or AC delco? Who knows the Summit might be decent...I haven't heard of failures from them, and half the price. So many threads about craptacular Chinese autozone special optis, and people half assing just doing the cap and rotor that still have issues.

Yeah I bought the summit brand. It was like 280 if i remember right, pretty cheap. The junk optis that did not work were from autozone. The maker of them was Cardone.
