1990 L98 Corvette Issues
Took my car to a shop because it had a dead miss and you could smell alot of fuel from the tail. The mechanic said one of the intake cam lobes had went bad. So he claimed he replaced the cam and removed the smog pump, replaced the cat with a resonator, and removed the smog pump. I paid him 850.00 for the total job. Upon picking it up I noticed it would miss when you would gas it to overdrive sometimes but when you let off it would go back to normal. I called him and he said the cam he placed into it was a slightly larger cam and it was running Rich so when I gas the car it might make it miss. He said a hypertech chip would fix it. Any thoughts?? I'm at a loss here

No I didn't. He claimed that he traded the old cam to someone who wanted a worn out one for a dirt car. The rebuild it to get past the inspections. I also noticed the pump is still in place with all the hoses removed and the little black part that was connected to the pump is gone. And the pipes going into the headers are plugged with the rubber hoses still inside but they are disconnected. But it doesn't miss all of the time. It just misses then I smell fuel then it goes away. It mostly does it when I go up a hill or I give it a decent amount of gas. I have thought about the o2 sensor but what about the engine temp sensor? Could that be the culprit? I have a feeling I just paid I giant was of stupid tax. But something I don't get is the guy is a well know mechanic who does good work from what others have told me about him. Tbh I don't think I will be going back to him.

Old or new, if you don't know or they think you don't know, they will rape you like a $2 ***** in a men's prison. My wife holds a Master's and a Post Master's degree. She makes life and death decisions. All she is allowed to do is pick up the car at the shop. It is paid for already. She does NOT talk to the SA or the mechanic. Any questions are to be sent to me and me ONLY. Why? Either she will confuse the mechanic or they will see someone walk in with ***** and a skirt and find some way to upsell. So the oil change might end up costing $40 but there will be $500 of "necessary service". Jiffy Lube tried to sell her a CHMSL for $8, an air filter to replace the aftermarket one we have and who knows what else. Being ethical, they stopped short of blinker fluid and muffler bearings.

All that aside it still doesn't fix my issue. The injectors are fine I tested all of them myself. I have a new engine temp sensor that I have not put in yet and I'm wondering about the o2 sensor. The issue is that I'm about to go back to college full time and I want to take the car with me. So I really need it fixed.

On May be lazy and ******** might have left something off. Change O2 and do the basic thing. Check for spark, fuel delivery and change the injectors.

You got took. A cap at the valve? WTF? I unscrewed the valve and put a pipe cap there when I did mine. You take the air pump off and put a pulley there. Sorry but with the work I see and hoses lying around, I have little doubt that he didn't replace the cam. I mean, you have the right to have your used parts back since you bought them. Who the hell said you can "give" it away to the local guy?

Picture 1 has a rubber cap going to the valve. Really??
Picture 2 has a brace going to the air pump. How is it bolted in?
Picture 3 has a kinky hose going to it still. WTF!!
Picture 4 has a pipe doing what exactly?
Sorry but I really don't see much work done. I could have gotten drunk and done a better job on my F-body and Vette. OK, I lied. I was sober on both and the Vette was done by removing the engine and replacing it with a 383 and I didn't assemble those items on. I forgot.

Who are the "others"? If you get someone that doesn't know much, WGAS what they say. I read up the procedure and I watch my mechanics work till I gain trust in them. At which time, I will randomly show up during work time to see what gives with donuts. So if they get cute ideas, they have no idea when I will show up. I only talk to the SA to tell them what I have decided to do and how long it will take based on my conversation with the mechanic. If I see them follow procedure, donuts and maybe a tip. If not, they better have a good explanation for the deviation from procedure.
There was a knowledgable MB tech that would do brake flushes by sucking out the fluid in the reservoir and replacing it with fresh fluid and charge for a brake flush. MB wants you to do that AND pressure flush the lines but most customers don't watch or know so he does what he does, cuts corners and get paid. I don't use him. I talk to other mechanics and when there is a common theme that "Mechanic X cuts corners.", I make sure I will never use him to replace a screw or fuse.

I see some tape on wires a unhooked ground and miss matched sparkplug wires. The temp sensor can do some strange things too. How did you test the injectors?
