I have an 84 corvette that the car hesitates very bad like it has no gas i bought the car with all the conversion work already done

blown head gaskets would explain all of your issues
sorry to be the bearer of bad news but 191,000 miles is a good run if you had it since new

Yea , those crossfire injection vettes can be a bear sometimes . I had dealings with them 84-85 - 86 working as a tech at a chevy dealer . Don't remember much about them , haven't heard anything about them for long time .

How's the fuel pressure ? Have you put a fuel gauge on it ? I would imagine you don't have a Tech 1 scan tool ? What's the map sensor voltage at idle ?

Well,if you have not done so already. Get a transmission filter kit.Change the fluid,replace the gasket. Transmission fluid does lose viscosity. If you have already done this,i recommend a ****** shop.It could be any number of things inside the transmission,like linkage.

id check ur transmission mounts first and make sure ur transmission fluid is full and should be changed if its been at least 60k since its been done

Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.

Give it a good tune up. Change the cap and rotor, plugs. Make sure that the plug wires are in good shape and not broken from heat.

My 99 Audi A4 2.8 Quattro was havinga problem starting at times. It would idle poor upon start and then it would come up in rpm where it should be. I had hesitation from a start and after coasting for more than 5-8 seconds, the car would shake violently upon acceleration at about 1/3 throttle. I cleaned the Mass Air Flow Sensor. This helped but did not solve all my problems. I then replaced the Mass Air Flor Sensor. Little to no change there ($108.00). Lastly, I replaced the spark plugs. I bought Bosch plugs ($4.82 ea.). This got rid of all the symptoms. I had bad lugs and possibily a dirty MAF!
